So when I look at equipment drops right now, I basically do this:
crude - auto-salvage
fair - auto-salvage
average - auto-bazaar
superior - compare to current equipment, if worse, bazaar, if it has a prefix I might admire it for a bit and then bazaar it
exquisite - if it has a bad suffix or only 1 PAB I bazaar it
magnificent - keep because I don't know how to evaluate
Do these seem like generally good rules of thumb?
Basically I have no idea how to evaluate equipment. I've read the wiki page on it and stat ranges - and it's funny even back in 2013 I had trouble making comparisons. A huge issue for me is, since I'm only level 200ish, I don't know how to scale equipment so I can compare it on an even level with some of the level 500 stuff I see everywhere. It's really taxing trying to evaluate whether your stuff is worth keeping.
Looks like a decent start.
If it isn't an upgrade for you, it isn't worth keeping.
As for evaluating Magnificents:
1-handers, 2-handers, shields, cloth armor, and heavy armor have three PABs. Light armor has four. Saves have two.
Not all Mags have all the PABs possible, and if your particular item lacks one, it will probably not be interesting to others to buy it. That's a pretty easy item to see and filter for, not necessarily the most important thing.
Prefixes and suffixes are pretty easy to notice and evaluate too.
One-handed weapons: Ethereal is popular for several builds.
Light or Dark prefix is very popular. It is even preferred over ethereal on rapiers due to 1h's mechanics.
The other four elements are mostly equal, though cold is favored a little, and fire us less preferred a little.
No prefix is trash.
One possible exception to this is a Rapier. If it is missing agi PAB that's fine (for 1h build users). It can also lack a prefix (though that is a pretty big detractor). As long as it is of Slaughter and very high damage and parry base stats.
Suffixes:
Slaughter is pretty universally popular.
Balance is useful for certain builds/options, and generally better than other prefixes overall.
Nimble/Swift nearly useless, though better than no suffix. Swift may be of some slight interest to others if on a wakizashi; Nimble may be of some interest to some if on a wakizashi, shortsword, or rapier.
No suffix is trash. Not sure if magnificent can even come without a suffix.
Weapons generally are rated for their damage first and foremost. Bring up the equipment popup with the "C' button for any gear you're evaluating. Mouseover various stats and look at the base values. After you do this for awhile, you'll get to know which stats are fairly high (and you can refer to the ranges in the Wiki too). There are also scripts, like HVToolbox which (among other things) faciliate this process.
Shields are only useable by the 1h build. While they have four possible PABs, they'll only ever have three of them. The ideal combination is STR+DEX+END (SDE). SDA is acceptable to many, though not ideal. DEA and SEA are trash. Less than three PABS is trash.
Block stat is the most important stat on a shield. Bucklers are all trash unless they have the "of Barrier" suffix which raises block. Kite shields are fairly useable and sellable if they're pretty good, but force shields simply have the highest block stats, so don't expect much out of non-force shields. The high burden of force shields is not an issue for 1h builds.
Most of your magnificent shields ought to be salvaged for a high-grade wood material, which can be sold for a decent amount.
A force shield with really high block stat may attract buyers even if it has trash PABs. Since Legendary shields are better, and shield is pretty important to the 1h build, they're likely to skip over magnificent shields in favor of a legendary one though. Middle-range legendary shields have better block than top-end magnificent.
2-handed weapons are all pretty much trash. 2h style is useful up to around the level 200-250 range, but popularity severely drops off at that point. The weapon needs to be legendary to really draw any interest from people after this point, and with nearly perfect stats to get them to even raise an eyebrow.
heavy armor:
Needs to not be missing PABS, and if it is plate armor, it needs to be of protection, warding, or dampening to stand a chance to sell. Most people are going to ignore it completely though, since even legendary plate armor is pretty cheap there is little to no reason to get magnificent. If it has shielding prefix, it might draw a tiny bit of attention.
Most people are interested in power armor. Missing a PAB is maybe less of an issue if it is of Slaughter or Balance. Protection, Warding, or Dampening with all three PABs might also sell well.
Savage prefix with often raise the value of the armor. Especially if it is of Balance or Slaughter. That's basically the jackpot of heavy armor.
ADB for power armor is also very important. Buyers are often willing to sacrifice other considerations in order to have higher damage.
Light armor:
Leather is all trash. Even peerless grade. Not even high-grade leather is worth much.
Shade armor is attractive to non-1h builds since it offers a lot of agility. Builds using light armor are very stat-hungry, so need all four PABs for sure.
Damage boost is very important.
Suffix: Shadowdancer is most attractive. Fleet is reasonably attractive. Negation and Arcanist are mostly trash.
Prefix: savage or agile raise the value quite a bit.
Cloth:
Nearly all magnificent cloth is trash. Mage is the most expensive build, due to high demand among the richest players in the game. So there is no reason for someone to bother with less than the best. They'll be buying legendary.
On the other hand, magnificent cloth can be salvaged for high-grade cloth which is pretty valuable.
You might get some sell-value out of a magnificent phase cloth with a charged or radiant prefix.
Staves:
Same as cloth. Mages will be the
most picky about which staff they bother to buy. Salvage for high-grade wood most likely.
That should get you started.
