Start by improving the pet mechanic. Specifically:
F1 Attack/(Toggle)Heel
and
F3 Move To (Ground targeted)
It would make pet controls more intuitive and allow the option to path pets out of harm's way, without requiring too many button presses and overcoming the fact that Guard/Avoid Combat cannot be hotkeyed, which would be a welcome QoL update if it did.
Axe (Mostly OH #4)
Dagger (MH lacks cleave)
Short Bow (Lacks damage potential on flanking which is hard enough to pull off in any competitive environment, and is still outclassed in PvE.)
Staff
Sword
All need love. So does Druid and I wish pets were an optional mechanic for them, too. Stowing a pet for skill effects and attribute increases would even improve core.
And give Soulbeast the second pet back, but instead design the drawback that your pet appears with the same hitpoints as it had before when leaving Beastmode, and when you switch into Beastmode, if your pet's health % is lower than yours, lose health equal to 50% of the difference.
Losing the second pet lowered the skill ceiling by so much, it's not even funny.
