I'm extremely conservative with all of my recommended Dragoon posts. I don't think we need more accuracy and attack bonus traits, though I'd welcome them. Dragoon is hybrid-ish in that we're relatively strong AND accurate whereas other DDs tend to fall into either or except during periods of higher acc under JAs that grant acc bonuses. Given that we have A+ Polearm, have tons of acc gear and 3 traits, our ACC is probably #1 amongst 2handed DDs.
Jump Mastery would be mitigated if they simply gave DRG "Critical Attack Bonus I". I always felt like we deserve it more than DRK, given that our DEX is naturally higher, we have multiple abilities revolving around Critical Hits, and we have multiple critical hit weapon skills. DRK has none of these, instead we were paradoxically given Critical Defense Bonus up to tier III.
True Pierce would be nice but I'd rather them make piercing weapon damage resistence more in line with blunt and slashing. Right now there are very few(if any) mobs that takes -50% damage to slashing or blunt damage but many that take -50% to Piercing. I think this was done because there are many more mob types that are WEAK to piercing so they felt that because more monsters are weak to it, they ought to make more enemies that are strong to it. Unfortunately the -50% penalty is absolutely,catastrophically devastating to Dragoon. I could understand 25% but 50% makes us laughably worthless. Hitting Naraka mobs for 50-60 damage in Legion while fully buffed and doing 400-500 damage weapon skills while everyone else is nailing 2k+ weapon skills make me very, very sad. I know "tomahawk, Banish III" but still.
Drachen Evolution is superfluous. Our Wyvern's DMG is actually quite high it's just that its Attack is low. I'd rather us get a Job Ability that restricts them from using TP during a breath or even preventing them from using breaths after a ws at all(since their melee does more than breath and breath charge delay slows down their melee). Additionally letting them retain their TP lets us get a nice bonus chunk of TP every 90 seconds from Spirit Link(drains half of the wyvern's TP, wyverns can get 150-180 TP every 90 seconds roughly, so it's almost a free WS worth of TP).
