It should be obvious why many people don't want this, weaker whales will have no chance at space time, weaker level freezers will have harder time vs more p2w/older ones. Some people worried cross events will get harder/impossible. Also i highly doubt they would start doing things by power instead of level, people are asking for that 4 years now, why do you think they will change it now.

just for the record i am from old server and i want cluster merge for 2+ years now because boring fighting same 20~ people, but it's very obvious it favours some and makes life harder for others, this will generally make game more fun for strong people and less for weaker ones, unless they change events to go by power which i think they won't.
