I realize there are differences between Ranged DPS and Melee DPS with Ranged DPS getting AoEs earlier. My main point I think I missed was to make Doom Spike earlier to establish it as a AoE class early on so later on when it got Sonic Thrust/Coerthan Torment/Geirskogul/Nastrond later it wasn't as much a dramatic change. Also looking at Nin and Sam as a comparison I would totally drop down from 170/200/230 potency combo to like 100/200/300 combo if it meant getting it earlier. I don't think it is asking much considering Drg doesn't have a Dot until much later than both.

Ninja gets Death Blossom at level 38 - 120 potency AoE
Ninja gets shadow fang at level 30 - 90 potency DoT

Sam gets Fuga at level 26 - 100 potency AoE
Sam gets Iaijutsu (Higanbana) at level 30 - 40 potency DoT

Drg gets Doom Spike at level 40 - 170 potency AoE
Drg gets Chaos Thrust at level 50 - 45 potency DoT
