Build your own symbiod?
Just an idea: what if the symbiods were to be added as a playable character where you could unlock various skills, abilities, and special moves?
You would only have one symbiod, and using a Mastery-like tree/points system, you could build up a champ of your liking. One tree for passive abilities, one for specials, and one for active abilities. You could then rebuild/reset the build as much as you wanted based on your needs. With a limited amount of points to spend across your skill trees, your build would never be god-tier but you could set it up to best suit your own fighting style. As you rank it up, more points (and skills) are unlocked. Maybe even limit the available skills to the champs you have in your roster (can't add Wolvie's regen if you don't have him).
Some suggested limitations:
- No team synergies
- No class advantage/disadvantage
- Low Prestige
- Not all abilities or specials available and the ones available would be a nerfed version of the elite (i.e. regen would be 80% of Wolvie). If you want the full skill, you'll still need the original champ.
- Skills are locked for the duration of the quest/war they're in
