Meleemancer is very pvm.. no? I'm kinda looking for a fun PvP build. but it's definitely a possibility (widowmaker+summon hybrid).

Heh amaze your friends, confuse your enemies. Watch them stack lightning resistance only to be fried to a crisp!
Ok yeah its kinda crappy as an actual pvp build and relies on certain gear and bugs but its funny as hell if you can pull it off and make it decent. A challenge for sure.
