That's a huge problem. Superior? Level 259? Weapon is by far your most important slot.
Heck, you'll probably have better results with an Average rapier.

Shadow Veil: 194
That's another problem, though understandable if you have to Cure a lot.

My light set seems to far out preform my heavy set atm...
Cure casts: 998 vs 1730
Mana Draught: 144 vs 247
Mana Potion: 31 vs 226
Turns: 28,361 vs 27,965
Damage: 1597 vs 1579
Although Power is significantly more effective than Light at higher levels, PF DwD is probably the place where Light has the biggest
relative advantage. In ordinary play, incoming magic damage is quite low, and often you can spot and kill the dangerous Sprites/Celestials before they get 100 SP. Incoming magic damage probably only accounts for 15%? of damage taken, and a lot of that is from plain attacks and MP attacks. But in DwD, incoming damage is much more frequently magical, and not only that, also much more frequently hard-hitting SP attacks. So heavy armor with no Resist will be at a serious disadvantage to Light
compared to normal arenas.
Is the disadvantage worth it? With enough quality gear and forging, you'll almost never have to Cure, so even if damage taken is higher than with Light, if you don't Cure anyway, it doesn't matter, so getting more ADB via Power is the best option. At lower levels or with lower gear quality, where incoming damage is still serious, it could be that Light/Shade is better than Power
on PF DwD, as you're finding, mainly due to Light's Resist.
There are a few things related to playstyle though:
(*) No use of Fullcure? It's great, especially with high Heavy prof and Jug on gears.
(*) Have you tried just using plain mousemelee all the time instead of using weapon skills? It's a lot less tedious that way.
(*) Do you have OFC? Once 8-9 monsters start spawning, using OFC at the beginning of the round saves time
and reduces damage taken by a huge amount.
(*) Do you have Stronger Spirit maxed? 20% spirit shield is the biggest way Heavy makes up for its lack of resist.
(*) Don't be afraid to use health draughts, they cost nothing and ease the burden on your mana. Same for health potions. Even health elixirs are only 80c or so.
(*) Dampening is no good on high difficulty SG arenas. You either want Power for more damage, Power Warding or Plate Warding for reduced magical damage taken, or Power Slaughter.
IA2 will significantly reduce your mana potion problem. You'll get it eventually, and it'll always be useful (unlike equipment which gets discarded), so you may prioritize it over anything else.
Although it's clear that with that gear, Light outperforms Heavy on PF DwD, have you looked at the stats for ordinary arenas? Heavy is at its biggest disadvantage on PF DwD, after all.
A good weapon will let you kill faster and will reduce Heavy' disadvantages, since monsters will be dying somewhat more quickly, so they'll have less chance to use their SP attacks during the later parts of a round. Even a random Average rapier you can find in the bazaar for 1000c will probably be better than the one you have equipped.
