As a matter of fact, we had that in mind. *grins*
The situation as it stands is thus; we don't have a healer, per say. However, I'm a forcefield defender, which considering I can already (at level 15, without enhancements) give you a defence of 25% (softcap is 45%, which I can get close to giving you (39.5%) with level 30 IO's), WITHOUT any defensive powers of your own... plus I'm putting out 18.75% damage bonus thanks to assault, with you doing an extra 13% damage to anyone I hit with an attack, thanks to Sonic's debuffs...
I am a Defender. I will not heal you. You will not need healing.
The other toys Forcefield gets to play with later involve area denial. Yontan is rolling a blaster, because if he sits at the back with me, all bubbled up, at level 18 I get another toggle that simply repels all enemies away from me. Thus, blasting happy, especially with the damage bonus and the defense I mentioned.
So! A common tactic with this is to have as many as 5 blasters with one forcefielder; this is on account of the area denial I mentioned, and with only 6 on the team, no bosses spawn... a boon for blasters with AoE. By level 32 you have 5 nukes cycling, and after they blow, they jog back into the bubble.
Now, you may still want a tank or scrapper, and if so, fair enough! I shall shield the squishies while you go to work, and increase your defense to all by at least 15% (without enhancements), since you may not be in range of my PBAoE defense toggle. Similarly a scrapper may find he suddenly has tanker-level survivability... but no built-in taunt. Anyway, all that to say that ANY character will add to the team, so make whatever you feel like!
Poke me on MSN, we can work out times and whatnot!
