I noticed few really concerning issues with stealth after spending sometime in battlegrounds. Let me state that I am not talking about balance. This problems are related with gameplay. It becomes even worse if you combine it with current (or ancient) bugs with vanish / stealth mechanics. For example, hunters' skill that shoots very fast (not quite sure about the name), or any projectile, will land if its shot. I am not quite sure if this is a bug or not but it is surely annoying with that hunter skill. Another bug is that stealth fades for no reason.
The actual problem that I want to point out is that DoTs...With subterfuge is gone, stealth is instantly removed upon receiving any damage. As you know, every single class and every single spec (save maybe arcane mages and maybe one or two morespecs) has dots. If your CoT is on CD, then you are basically screwed. You can not remain in stealth. Most of these dots last around 15-20 seconds. For a class that conceptually designed around stealth, this is bad design. Now you can argue that stealth in WoW is just there for opener but that would be from a combat perspective. Stealth brings many conveniences which I wont even bother giving examples. I often found myself waiting for debuff to fade to get back to playing. In my opinion, this is not a good design at all. I want to utilize stealth as much as possible. Subterfuge did gave you that opportunity.
In short, I find myself struggling with stealth mechanics due to bug or by its design and it frustrated me.
So...your thoughts?
