Good feedback, Holyfuryzz :-)

You're correct: the proc rate for the bow, 2h sword and 2h staff are different - and that's bad. I'll make them the same (per each weapon's activation speed).

As for the difference in ranged vs. melee, use of gap-closing abilities (Warrior's Beckon, Rhino's Charge) are meant to be the crucial difference that ensures utility for the Sword and Axe procs. However, since the Bow's proc hits too often and it can be done beyond max range of the gap-closers... it's not working as intended.
