In almost all cases I would prefer just more damage, I can already freeze stuff, CC stuff etc... for helpless.
Moonlance/Strike a chord as basically the only ones worth using. They are pretty bad when compared to adrenaline, quick cutter, and ranged double/triple hit ones and hunts end.
Oh yeah, but like the melee/ranged CC strikes are pretty eh as well lol. Like Dire Charge/Shot, or even Drifting Lotus; or Pin, which I've seen literally nobody take since the Shiradi rework.
There sorta aren't any caster strikes for pure DPS currently, like Dragonbreath is the closest and it got overnerfed.
I'm just saying it's more comparing Feydark Faerielights with Dire Charge vs comparing Fire Pillar against Quick Cutter.
Like Moonlance is IMO better than Sword Sings b/c the CC is guaranteed and the damage is in the ballpark. Adrenaline (plus some active) is better than Moonlance though, since it's much better damage & still has no-fail CC.
Hunt's End as a non-epic-strike ED ability is competing more with abilities like Echoes of Discord (esp with the heal), Shard Storm, Reborn in Fire (which heals enough to work on Skelly platforms), EA's MCMW, etc. It's a solid ability but even Tonquin's is competitive for leveling IMO. I'm totally on board with like Flaming Sphere not competing though lol, I'm not sure who thought it belonged anywhere with the word "epic" nearby.

As far as the OP, I would absolutely love huge buffs to Hellball, Spirit Blades, and Arcane Pulse, and a smaller but still meaningful buff to Ruin/GRuin (IMO add +50/100 per legendary level - would be a +40% buff scaling into the future).
And I would like more utility added to epic caster strikes, since they seem determined to not give them big damage lol. Have them give short buffs to you or debuffs to the enemy. I'd also like to see more stacking stuff for casters in raids, as an option to give damage back without breaking questing again.
