Troll war shud never kick?
 

As a dual wielding troll war in the 50s, is there any reason for me to use kick instead of slam?

Kick-stun at 55, but why use it when slam can stun and has a higher skill cap?

I plan to remove kick from my hotkeys, but there is times where I get boon and cannot slam...

Unless you have boon rolling I can't think of any reason to kick as a troll. Slam having a higher skill cap should increase both the damage and your chance to hit for stun purposes.

Question: Does Kick have greater knockback than slam? Might be relevant for unstunables like dragons and giants?
