I do two different reg build, and one of em doent use snipe.
I get mines first, then range, then stats or main. I focus on mines, maim, and stats till i get plenor and the 1750 helm. That takes care of manna problems. The I max Angelic furry to increase dps, and it gives you AOE in addition to mines to handle creeps.
For favor its usually poison dagger. This build focuses on Regs AOE damage and slows. It also focused on high auto attack dmg, and a fast attack rate. That combined with the gloves that give you a chance to crit, and you should be ok.
To be honest its actually more a support build. I find it nice becasue it slows the heck out of your enemy and makes you obnovious and hard to get. It also make it good late game to hold off mass creeps, and has decent burst damage potental.
And lasly it works well to control minion builds due to its aoe.
