Shield Bash turned into an AOE attack.

[Nektulos-Tuor]

If you did something like this due to diminishing returns Paladin would go from having the best stun of 3 tanks to having the worst stun, and one holy would make the stun go down to resisted. This would trickle into PvP and any content like dreadknights where chain stunning is a good thing. =/

Nice thought though, just wouldn't work to change the existing shield bash.

How about this then? A new status effect that isn't effected by stun's diminishing returns?

It basicly interrupts casting.
