That's what RAF, boosting and heirlooms are for.

I can't even count how many full and partial teams I've leveled up before settling on my current one. Heck, I've even leveled up toons I have absolutely no intention of playing just because maybe someday I might. I've stuck with the healer and tank on this one, but the rest used to be all warlocks that I replaced one at a time. And before that, I probably went through about 5 other "main" teams. And I'm not even a FotM kind of player, that's all just figuring out what I really, really liked to play as a team instead of as individual characters!

Can't get attached to anything with an evolving game, just play what you enjoy until it's not fun anymore, then feel free to move on to something else. At the end of the day, you'll still have them in reserve in case you want to dust them off.
Just gradually level up a team of everything and you'll never have to completely reroll again.
