The bare bones skill trees for the sub classes is what's killing me. They are vastly uninspired. There some exotics that work with the trees but there is hardly any synergy. Youd think each sub class would have more synergy with their abilities. Namely the Hunters Dodge to reload and pretty much all the Titan Sub classes with barricade. There is a exotic chest for Titans where you can produce a orb and get a burst Heal but that's the kind of thing I expected in the sub class. I was expecting perhaps a tree for titans where the Tower Barricade reflected dmg back in one sub class. Or dmg absorbed by the Barricade gave you a shield that based the percent of dmg it blocked for its duration or reduced your grenade cooldown based on how much dmg it took. Maybe even a tree that said "You can shoot through Barricade but only when your grenade/melee isn't on cooldown" The Hunter's dodge to reload hardly has as much synergy as the melee version has in its own class. Idk, I just expected more and these trees lack build potential. Especially for PvE. I play this game for the PvE and this sucks.
