This idea may have been discussed before but I feel like it would increase the complexity and add flavor exponentially.

In addition to new content, worlds, dungeons, talismans, relics etc. (and this may sound pretty basic) but what about having a future world allow for an Eddie and FOUR toons rather than three? This would allow for different syngergies as well as potential weaknesses to exploit. I feel like if I could just have a 4th toon I’d be able to create a team that is really fun to play even if it’s not the strongest. If a 4th toon cannot be fit without losing graphic quality how about a swap ability like with Eddies?
