If AST's Malefic is boosted, would it be the same as WHM Glare or higher?
WHM still has the problem that it can't weave any oGCD into a Direct Damage Attack (Glare) while AST can weave in cards or oGCD into the same GCD as Malefic.

So if an AST's Malefic were to be boosted, that would mean that AST would have three steady damage sources
Malefic
Combustion
Cards

which would have great uptime vs a WHM's Glare and Dia.
Oh but what about Assize and Blood Lily?
Assize = once every 45 seconds, 400 potency/45 seconds (if actually fired every 45 seconds like clockwork)
Blood Lily = All this does is tell us to use a fourth GCD (first three for lilies to heal) in order to recover three glares vs a Single Target (savage/ex fights) but great vs Mobs.
So its Three in the Time of Four.
We still get more DPS vs a Single Target from casting FOUR glares.

In the very least when we are forced to move as WHM away from AoE circles, we can respond with Dia, Regen, or a Lily Skill to save our GCD from being consumed due to movement.

So if you match an AST to WHM raw damage and combine their cards.....(sorry but PoM + Thin Air + Endless amount of Glares do not beat out cards ever)
They would always outDPS a WHM if it wasnt for their mana regeneration problems.
