i guess it could be implemented, but imho it should be done with great restraint.

example: a staff that lets you lob a far more powerful version of the fuling shaman firebolt, but with very high cooldown and/or expensive ammunition (one surtling core recharges 5 shots perhaps)

....come to think of it, only a big cooldown would keep it in check, as it really doesn't take much to make a surtling farm....

Ok then let's say you get X shots per day and that's it, like old style D&D.

and make every staff require a compoment sold by Haldor at like 1k, so people don't make a ton. Or make a global CD. Man i'm brainstorming here...
