First off, i say 5 secs cause of the get up animation. 2nd maybe my CC break is on cooldown everytime but all the times i've tried to use it on that hidden strike knockdown, it was greyed out. not sure if you are talking about the stun or the actual knockdown(im talking about the knockdown from hidden strike). As for it happening all the time, no it doesnt but of course everytime i meet an OP its from that combo chain. 3rd, no the OP takes me down to like 50% by the end of that opening chain(if not lower). Now im only wearing 2 pieces of champ gear and the rest is the level 40 moddable orange pvp stuff. So never really inspected em or know the details but regardless, they drop me faster than any single class ive seen.
Oh and to theravenzone, maybe i guess. I'm a merc so im alittle bit squishier i guess with no offhand shield generator. No idea in all honesty but regardless i think they need to tone em down on the topend dmg they do, not completely neuter em.
