Numbers wise, Symbiosis effects are looking very strong

Especially since all skills seem to get the full bonuses from Symbiosis stacks with one point invested. Having access to 50 stacks (75 with a +5 fusion friends-y COM if those exist) seems crazy strong. Symbiosis stack sustain while mobbing probably isn't so bad, and hoping Storage Upgrade+ Optimization would be enough to sustain them otherwise. Both nodes also snowball their sustain with your amount of Symbiosis stacks. I'm guessing In Memoriam would be a must too.

I don't care much for her actual pet, but once I get to play Loveless and lv her up enough to test this out, I'd be curious to see how this all plays out.
