i think i haven't say it enough but switching Gravity and Combust II , YES YES YES YES!

i like those suggestions but one i would love with the actual royal road effect, is when you get the "party buff" royal road, you don't get a penalty of 50%. I don't understand this downside when you have to give up one buff and wait 30 minimum to spread your next buff. You should be rewarded for taking time/risk of building a combo.
