I wish the upgrades over i190 were more clear. Sometimes I think I'll lose some dps numbers if I'll upgrade. For example:

Prototype Gordian Gambieras Of Casting
Vitality 48
Intelligence 53
Spell Speed 33
Critical Hit Rate 47

Antiquated Caller's Sandals
Vitality 54
Intelligence 57
Spell Speed 37
Accuracy 53

I don't need more Accuracy (gonna be a wasted stat) and I doubt 4 Intelligence is better than losing 47 Crits. It also gives +9 defence, but my MD is 1373 already so I don't really need it.
So what should I do in this case, buy a whole bunch of nothing useful to improve my performance for 495 eso just because it has higher ilevel?
