to pvp with an MA sin while recharging off a town summon druid's bear every 15 sec?

ofc

pm toeshank for full gm pvp ruleset

absolutely BM

But then how am I supposed to duel as an MA sin? Every time I try to telestomp them and start to build charges they kill me even before I can get my cobra charges in.

can maybe chime in

barb bo and town buffs are verry gm

Well Blizzard doesn't make things based on PvP at all so that is a solid enough answer for you.
They made that sin spec specifically for PvM lol.

yeah I wish they'd think about pvp too... just some small tweaks here and there could make so many more builds viable

I will say it's more than likely broken if it were gm to pre-charge that shit though.
I tried to PK a sin in chaos while he was charged, albeit it was a non-mb mf hdin but he 1 shot me lol
