There are a few things in the game that kinda could use some fixing at least imo.

1: Paladins threat generation needs to be upped, Shield Oath needs to be lowered to level 30 (same lv warrior gets their tank stance) and sword oath can be upped to 40.
Paladins generates much less threat than warriors mostly because warriors hit harder as a whole, the pld skills could use some adjustment so they generate a tad more threat, especally flash and provoke.

2: Provoke.. Am I the only one who finds this useless? When I use it properly (which is when someone else has threat) it sets me back at the top of the list, however, it doesn't seem to add any threat itself, so the very next dot tick, or hit from whoever had threat just pulls it right off again. Easy solution is just add a medium to high amount of threat on provoke. Because as it is I find it pretty useless.

3: GCD the gcd really needs to be lowered to 1.5s or 2s.

These are just 3 things I feel could use some tweaks.
