Was a little bored the other night so spent a little time trying out the trolliest possible builds. Favorite was a 0/25/30/0/15 blackwater variant with perplexity runes and limitless confusion application (clone deaths, interrupts, shatters, scepter/torch, chaos armor, etc.). Confusion is still pretty crappy, but with so much invis uptime combined with 1200 distance blink and six-second phase retreats, you become the ultimate mesmer troll.
Anyway, anyone have an even trollier build than this?
