Should I retire my 60 wizard?

[sox7d]

Grouped seb last night with my three stuns, sunstrike and c2 and bard, and it didn't seem it mattered how well I interrupted or reserved mana, it was a joke compared to any melee's sustained dps. Thinking of just stripping my character and rerolling. wtf were they thinking with this class, they had two fucking expansions to fix it. Someone give me a reason not to.
