We have a handful of good traits, and most of our Alchemy line is good, but our grandmasters are pretty bad and our other trait lines lack internal synergy.
If you want an example of a trait line that’s well designed, look at the Guardian lines. Almost all of the traits can be used in synergy with the associated stat boosts and other traits in the line.
Some traits that should be added in a rework:
-Trait to reduce the cooldown of turret skills and their overcharges
-More Gadget traits in general
-More Toolbelt traits in general
Some traits, like Scope, are useless and should be removed.
Admittedly, Rangers also deserve a rework, but this is not the forum for discussing that.
