Guild Wars 2

So http://wiki.guildwars2.com/wiki/Stronger_Bowstrings
Lists that both Dual Shot and Fan of Fire become guaranteed projectile finishers.

So is this really a bug. or is this working as intended. If its a bug how has it managed to avoid the hot fixes? Isn’t there some sort of obligation to fix game bug. If it is a trait feature could we get a tool tip fix.

Yes, they have to fix bugs, but how long it will take is another issue.

I also would like to hear an official say about it, imo it is just an tool tip error not showing it in the description.
