If I had a change to make to him, it would be to take an arbalest skill, which would replace the spell flinging most of the time. Fire arbalest, then become beasty and tank.
Sometimes I am almost feeling like I am playing a pirate ship or shooting commando.
For me basically every fight starts with:
-Positioning dudes, Fighter a little bit infront of all the others, others mostly in broad line
-let the fighter do the first shot (longest range)
-immediately after shot, switch to melee, and give move command to overwrite automatic "must attack someone" AI
-then wait a couple of milliseconds till dudes are in range of other characters
-dependent on opponents either let all the guys shoot on the same or on different targets (2 pistols + 1 arquebus + 2 wands).
-After first shot from pistol guys switch to melee, give movement command to overwrite AI
-Arquebus dude (Aumaua Chanter) switches to next of his three Arbalests to shoot again
And that's actually just the first 2 seconds in combat if there wasn't pause.
What I find annoying though is to make sure that all the Pistol, Arquebus and Arbalest Guys need to switch through all their weapons after each fight as you need to reload each one manually
