For Acolyte/Novice/Adept Power feats, you can choose a new power every time you gain a level. No retraining needed. So you can just retrain the MC every level, and snag a new power for free.
Seriously, this guy deserves a dedicated bed - I mean thread - pillow case (with pillow) and all. What party wouldn't love to hang out with this soft dude? The only thing he might lack is Brew Potion (for an endless supply of White Russians) and a "Pyjamas Armor".
Test your PC builds' combat prowess and pit them against other builds at the Core Coliseum - the online D&D arena.
If you want to expand on the most powers from classes or whatever into the most options among classes and races, you could go Revenant (Deva) Bard/Resourceful Magician/Soul of the World
As a bard, you automatically have the ability to choose multiple multiclass feats, RM lets you take powers from any arcane multiclass taken by 16; from level one, you get options from both revenant and deva feats; and with soul of the world you can choose two more races, another class to choose powers from, and finally a feature to temporarily swap any encounter attack power with another of the same level from any class from one short rest until the next, where you get to change it again. You can add power swap feats on top of it all.

The Fighter is ludicrously over-supported. The Wizard is almost as badly so. They should hybrid in a spectacularly poor fashion, as they have next to zero synergy. I would like to see some kind of hybrid Wizard|Fighter that both takes advantage of their ridiculous mounds of support and doesn't just ignore one side's tricks and powers, resulting in a playable character. So many builds benefit from MCing Fighter just to pick up their toys (I have a friggin' Invoker who gets a huge boost out of it. An Invoker!), and there's a smaller but still extant set of builds who do the same thing with Wizard (though they've cracked down a bit on that with some nerfs) . . . let's see how well those toys can prop up an otherwise miserable hybrid.
I have no idea where to start. Maybe go genasi for Elemental Empowerment to make STR/INT not a total waste?
