What role would you like to see covered from a third e-spec? Below it's a set of roles which I think ele still miss and would definitely benefit from, if somebody want to propose an additional role, do so possibly with some reasoning.
900 range support/burst is already covered by scepter
Melee burst PBAoE covered by sword-d/d
1200 AoE range burst/support covered by staff
I really feel like ele should have had access to single target 1200 range since launch, focusing on damage avoidance rather than heal tanking would solve loads of issues while opening many doors . A single target burst from 1200 range should not be plagued by after cast and delays like it is for staff, its non-AoE nature would justify the addition of fast cast and lack of rooting animations
