Can Smash DLC be done right? If so, how?

I don't think so. Character DLC could mean pay 2 win. Even if it sucks, it is still a disadventge over anyone who doesn't buy it. Stages? Sure, that's fine. But characters? You would need to learn the strategy, is it heavy or light, hits hard or fast, etc. And the only way to know it, is by buying it.
Besides that, having to test a single character to check how it battles against every other character would make it a hell to develop.

They could make it so you can't play with people who have the DLC.
