I don't really see the point in playing Grindfest anymore, and least for myself. The arenas already take so long that I don't even do them all every day, and I get far more good items and equipment from playing the Lv.100+ arena challenges than I'll ever get from Grindfest. I've gotten tokens from the arena too, and proficiencies are easily farmed with the first page of challenges since I never need more than one or two hits from the Regen to complete through Killzone. That pretty much eliminates all reasons for me to play Grindfest.
Maybe that's because you're not supposed to grindfest your way to 200. (IMG:[

If you remember, the grindfest was mostly added as an afterthought. The arenas will always be much faster, but again they are riskier if you play it close to your level.
