Powerful not OP. I can barely count on one hand about the number of assassins that make this class look OP. They need to revert the change that was made in 1.2, give back some armor and self heal and nerf the damage more. That's the only thing I can think of that will "bring the class in line with other tanks", even though we have had two nerfs this change would not bother me. Then the class can be useless in rated's and everyone will be happy.
And you keep saying the class is OP...why is that? Do you find deception or madness OP as well?
My gripe with asassins is not their ability to counter me, (although there are many terrible that cannot kill me), my gripe with them are how universally good they are at everything. There are tons of things that i dont want to see in this class, force speed while cloaked for every spec? This should be in deception. Root cleansing? Why a tank that can cloak and also have force speed, and also incredibly high defense against which legshot can miss, deserves to have a root cleanse? You have tons of features like these that have been added just for the sake of versatility without puting serious thought into what exactly should the weaknesses of an assassin be.
All this talk about sins not being very good and useful when in the zerg, oh please. All those stuns and CC are certainly not very useful.
Developers stated that they want to balance the game arround 31 pts specs, not hybrids, yet you are full of it.
