Starting Lets Play Soon..Who to Play as?

[TheIronVal]

So, me and 3 friends are doing a lets play soon. Our team is currently
1 DPS Aprentice
1 Tower Huntress
1 Tower Squire

I, on the other had, am ot sure what to do, and I have a few options. I am thinking either
Tower Initiate
Tower Summoner
Tower/DPS Series EV
Barbarian

We have 2 players new to the game, leaving me and another player with the knowlage on how to play the game. Any feedback would help!

I would suggest summoner just because it has it's own limit on units and extra units is always nice. Not sure if this "Let's play" means you're posting a video but it might be a little boring for viewers to watch. For action then I'll say the barbarian.
