Finn is not the problem, cp3o is, just like revan was before and a long line of utterly poor design choices that ended in a rather extreme power escalation. We all know the reason behinde it is the revenue it brings due to the extreme wallet warrior factor to them.
You can argue to all infinity about what would be the better choice to change but it will come down to primarily
a) not nerfing content a very small group paid alot for
b) not adjusting the raid due to alot of other teams being affected
c) adjusting a free toons z ability is very much easier to get away with
I have given up on it already. it's wow ilvl scaling all over agian, when are we getting our first game reset ?
