With stuns and interrupts being available to all tanks, are they going to design encounters that take advantage of these skills more, or are they still going to be relegated to mainly stopping attacks in trash packs?

To add onto this, as I know not everyone reads all posts, an idea I have thrown around is to allow attacks to be stunned/interrupted, but still allow the attack to go off, but with a different effect or attribute. EG. a raidwide does damage and applies paralysis, if you stun the boss, the attack still goes off, but the paralysis is removed, making it a pure damage raidwide. Of course, there are many possibilities with this system that could be played with and I think it could pave the way for more unique mechanics.
