Am I the only one that struggles with how to use Wyll in the party?

Wyll sounds like he should be a bit more 'kick ass' than he is. In combat, he seems to miss about as much as he hits and as a magic user, he's kind of a one trick pony with his witch bolt. I had hoped that he would offered up as a option to replace Laezel as the party 'tank' but in practice, I find him the least useful of all the possible NPCs.

I've played through the start 7 or 8 times and Wyll is the npc that I use the least. In the dialog conversations, he comes off as this big hero, but either I'm using him wrong or maybe he's just a 'hero' wantabe.

So if you are getting milage out of Wyll, how are you using him? I honestly like the character, but if I had to vote someone off the island, he would be my first choice.

Thoughts or suggestions?
