I know there are already a billion threads about the upcoming hidden strike/jarring strike nerf, but I thought I may throw my two cents in the ring too.
The reason this is such a problem is that the hardest hitting move an Op has can also be a 3 second stun. Rather than making the stun attached to it sufficiently bad nobody will use it anymore, why not give the Op the option to leave stealth with either a burst OR a stun.
People may hate the WoW comparisons, but I think the way a rogue leaves stealth is much better. They can burst the target, stun the target, or DoT the target. These options prevent them from having any one move coming out of stealth that seems over powered.
Additionally, rather than giving the out of stealth stun full resolve, why not make it a trade off to continue the stun with debilitate or keep the damage going full force (again, like WoW with the rogue's non-stealth required stun instead requiring combo points which could have been used for damage instead). This suggestion will probably sound extreme, but have debilitate put Shiv on CD. Then you are missing out on both the damage of Shiv and a TA in order to stun lock the target.
It is the lack of options that are leading to these situations which seem over powered to the guy laying face down for three seconds after getting crit for 6k.
Any thoughts?
