Every week or even every month. there should be some sort of “tower” event. whether it be a faction one or just solo. in which the higher up you get in the “tower” the better rewards you get. it would be tallied via points which can be obtained from many things. such as how fast you complete each stage. how many 6* you use. if you have weapons equipped. etc etc.
rewards can very per “tier” lowest being trainer/mods to the best being a old ascendable or a “nightmare tower” toon. specifically made just for that.
Thoughts? i know for a fact theres gonna be a bunch of people screaming “p2w event” but lets be real. name one current event thats “f2p”?
