Apologies if this is a silly question, but I don't have a ranged specialist toon and haven't run with a great Xbow before.
Someone mentioned the knockdown ability of Great Xbows earlier.
How do you factor that into the equation?
Raw DPS is one thing, but if any opponent is knocked on their ass, they aren't doing any damage to you?
Is the knockdown effect noteworthy enough to consider in a more holistic equation encompassing weapon effectiveness?
Are bosses immune to the great Xbow knockdown?
If you vorpal on a GxB it will no-save knockdown a mob if it is non-boss. Be advised that the game no longer gives helpless damage for the knock down. But it is still helpful in damage mitigation. The devs broke the knockdown with the implementation of the Xbow changes during the mech rollout, initially claiming wasn't broken, and then claiming it never gave helplessness, and when that was proved wrong conclusively Severlin changed his tune claiming it was his intention all along.
Helplessness would have driven a whole different set of builds if it had remained.
A big consideration with the new mechanics is that when they are using a GxB they will vorpal on 19 or 20, and that will proc both the no save knockdown and any other vorpal triggered effects you may have on your weapon, feats, epic destinies.
Just to be clear, yes, bosses ignore the knockdown effect, but not any additional vorpal triggered effect the character may have.
