Happy to help! Glad to hear the partial-IK is working out so well; the rest of Hell should be relatively smooth sailing now I expect.
If you load your inventory with AR charms and ideally have AR on a rare ring (plus the AR/Dex on Ravenfrost), you can probably get away with losing the Angelics because of the huge AR bonus on Berserk. My AR was ~12k without Angelics, and that was plenty high enough to hit in A5 Hell. I had decent charms but nothing great, as I keep my gear on each character so it was far from my best stuff collected onto this one character. I also used much of the same equipment as you and never had to spend a single hard point in Dex, as I believe you won't either. So losing the Angelics is very doable. Highlord's would really boost your damage, if you happen to have one of those.
