Guild Wars: Mind Blast Arena

Given that my computer has decided to melt whenever I try to play Bioshock, I was back in the Random Arenas last night. I was running a variant of a creative Mind Blast build I'd seen posted by Patccmoi:

E/Me Clumsy Mind Blaster

12+2+1 Fire Magic
10 Illusion
8+1 Energy Storage
Mind Blast
Glyph of Immolation
Liquid Flame
Fire Attunement
Clumsiness
Imagined Burden
Flame Djinn's Haste
Resurrection Signet

I subbed Liquid Flame for Fireball and Glyph of Immolation for Mark of Rodgort, because I'd rather avoid 2s casts and the Mark wasn't sticking a whole lot.
Easy to play, decent damage and melee shutdown and the all-important ability to kick an assassin in the nuts. I'm not sure that you really need Fire Attunement but it doesn't hurt to have it. No self heal, so knowing when to run away is pretty important. For the most part, you can just load up with Attunement and a Glyph and then just alternate Mind Blast and Clumsiness on a hapless melee type, while keeping another one near-perma-snared with Imagined Burden.
Don't forget your high energy (+30e/-2r) equipment swap - very important for Mind Blast builds.
