Dnc has an attack buff that increases 5% for 1 min with a 1.5s recast
While DRG Dragon Sight buffs attack by, 10% on Caster and 5% on partner, for 20s with a 120s recast and limited by distance of 12y during use.

Dragon Sight needs to last longer to make it worth the use compared to the dnc.

Stardiver comes out quick and hits like a normal jump that can only be used every 60s if you can get Life of the Dragon up. It needs to have the same impact feel as Dragonfire Dive.
Damage wise for now it's weak it deals about the same damage as the Dragonfire Dive.
