Thus, with that in mind, I propose removing "Life Surge" from the Dragoon's arsenal. Before you tear into me, about lowering the Dragoon's already lack of survivability, a Dragoon typically would not have Life Surge up when focusing on damage dealing – Power Surge should be their main focus.
Ok hold on lemme tell you somethings from a drg aspect. In a Party yes we dont use life surge because
1: it consumes tp to still be active
2:it doesnt effect ws so no drain from ws if u have life surge
3: power surge is more useful since its um power surge :P

BUT!!

its usefullness comes when soloing or farming imagine having to SB ur unfinshed Gae bolg u dont wanna use Power Surge since it decrease ur def in exchange with attack power. so basically if u are a soloing drg you probably want to stick to life surge and not power surge and since u have "Heavy Thrust" which is a long ass stun to a mob u can recover HP from life surge that way. And you seem to have forgoten Dread spikes which is a nice ability if u time it at the right time in a pinch against some bosses Physical WS when u know ur F***ed "100-tonze , Darnus ws's forgot its name, some skirmish bosses like the tree or the golem. <thats my view anyway>

and no am not saying "Hey we dont need classes to survive" i know that switching to LNC gives me more Survival chances.
