I tried asking a similar question a few weeks ago and got very half-witted responses.
My concerns are in movesets I don’t have, not in potential buffs/nerfs to existing movesets. We can’t predict which moves are going away, but you can TM your way to as many optimal movesets as possible and hope that they don’t get nerfed.
Example:
Machamp with Counter/ Dynamic Punch
In case either of those moves go away, you’re going to want your under powered Machamps to have that moveset, I assume. Other people however are excited at the potential buff of Close Combat. If that even more unlikely event were to happen, you would want one of both...
I’ll be sticking with the current optimal moveset and changing as many as possible to C/DP.
