I don't feel like this problem is even rogue-specific. It's super cheese that any character who presses "C" behind an enemy can cause them all to sit still and pass their turn, and a minor 1-point investment in either Polymorph or Scoundrel allows anyone an invisibility skill.
I like the idea of enemies searching around for the stealthed person if no visible targets are available. This sounds like most of the fix right there. Although, I have seen enemies smart enough to grenade and Phoenix Dive stealthed and invisible units, but no attempts at moving towards the area otherwise.
For bonus points, I'd like AI to search for stealth/invisible targets even if other less-desirable targets are available. For example, If I've nearly killed a healer who suddenly disappears, and all I can see is the tank, I may just toss a grenade or search the last location of the near-dead healer before swapping.
Also, I'm pretty sure Armor and Magic Armor are already fully replenished on enemies after a few seconds out of combat.
As for the original suggestion of freezing cooldowns, that seems like it would infringe too much on legitimate stealth use. A more-targeted fix is necessary.
It feels good to know I'm not the only one who doesn't see this as a rogue-specific thing. Balancing rogues is a problem in its own right. The AI is just too poor in dealing with sneak. I made this thread about the cooldowns because I thought it would get attention and get people talking about this problem, but I think it would be MUCH less work for the devs to take my suggestion vs. revamping the AI, which I totally agree should be the main fix to this problem.
Still, I want some opinions about how much of a punishment freezing the cooldowns is REALLY. If you're playing Rogue doesn't most of your damage come from regular attacks anyway? The way I see invis, there is this HUGE advantage that no one seems to really value which is the ability to REPOSITION. This is a HUGE advantage in my opinion. Also, people would actually have to think about the best time to use invis in relation to their other cooldowns.
