A ranger with correct AA's, Elemental/Time/GoD and OoW raid dropped gear can pull off crits for over 2300's when True Shot disc is burning.
With Every set of Critical hit AA's done, Combat Fury, Fury of the Ages and Veterans Wrath a Crit is usually 3 out of 5 hits. If Melee stats are maxed out with gear, Wunishi(spelling), Ranger Buffs, Enc haste, bard song and FA/SK proc some will proc at a amazing rate.
This bow is in truth very very good, and in a way makes sense to take it from the game, due to the way Sony nerfs content due to a roll of the dice.
If looking for a truly good bow, please check out the Bow drop from Riftseekers Sancturm or even better yet the bow that drops from Aungish, though the bow from RS is more likely a commodity (spelling) that more will be able to obtain, due to the difficulty of tackling the CoA key quest.
Hope that helps out
