Update to Siege Weapon Damage - Concussed Debuff

Robbmrp

For Trebuchet and Ballista hits, why not lower the damage by 10% and add in a new effect called Concussed. Anyone within the siege range would be knocked down similar to what meteor does and hit with a concussed debuff that slows movement speed by 30%(15% for Ballista). As it stands right now, when you survive the impact you just purge and go about your business. With a Concussed debuff on these, it would penalize people for standing in stupid. I'm just as guilty as anyone else on this, as a Templar I can just toss down a Ritual of Retribution or Extended Ritual after the initial hit and continue sieging away with no worries.

Thoughts?
