I guess how I would balance is one the following:
- For every (two or three?) mono pillars/towers you own, you get one extra quantum of that type.
OR
- If your deck contains only the pillar matching your mark, your mark is increased by one (though this might stack too much with immolation and supernova builds)
I prefer the former option. Ideally, you would want to balance in such a way that competitive duo and trio decks are possible, without resorting to the 'rainbow lite' option.
Anyway, this seems like it might provide non-rainbows with a significant boost, but still leave the standard rainbow FG-grind deck capable of its 40% or so win rate.
(btw: yes, quantum is the singular form of quanta and I'll hear no more about it =)
