Yep, you need DR, Yep, you need resists. Yep, you need a little faster cast for FOH.

The big question is are you legit or not. However, something that i can recommend whether you are or not is to have a Wiz Spike/Herald Of Zakarum on your switch weapon slot. Use that for FOH casting, along with Conviction.

What i recommend is (if youre on east, and illegit):

.08 Gaze socketed with Jagged Jewel of shout
.08 Bugged Valor, havoc'ed perhaps
Ith Zerker
Bugged String
Cham Stormshield
War Travs/soul spurs/waterwalks/gore riders all good
For gloves, its your choice. Get some 20 ias/knockback/dex/str gloves for some fun stunning if you want.
Highlords ammy/.08 saracen's/atma's/maras are all good
2 viper whorls/cgrips/bk rings
