u have IC which mean your cast will never get interrupted even with 190aspdWell it doesnt really get interrupted.. It kinda just wont let you cast it. :-\ Maybe its just me.. Anyone else?
Perfect IC (150 dex) is impossible to be interrupted by attacks, however if you have 149 or something that is near IC you can still get interrupted. If you have true IC though, then you can never get interrupted so it probably is position lag or after-cast delay or something.
The only possible case where such a scenario can happen is position lag from flinching.Actually I have IC and Eddga...when I stand in one spot I have to remove eddga because for some reason when I get hit while wearing them I can't cast at all Unless I move. /hmm
Basically, you try cast a spell at a particular location that requires walking, but a monster hits you, so you do that flinching animation and you think the spell gets interrupted.
If the above scenario is your cases, I would suggest Eddga not Phen
