Machamp with legacy Karate Chop/Cross Chop

He should be a great choice if you are a player that like to dodge a lot. KC charges energy really fast, while CC has very low cooldown. I still think it's a slightly worse moveset than C/DP, but by the looks of it, I think it should end up as the 2nd or 3rd best moveset for Machamp, possibly tied with KC/Submission. I haven't tested KC after the update but I'll give my 1674cp KC/S Machamp a try this afternoon.

Personally I would wait until I evolve C/DP (I got dual steel moves on two 98% Machops I evolved this weekend), but if Machop is rare for you or the level/IVs on your KC/CC is great, I'd take him to 30.

Good move set. I'm using my old Machamp as prestigers versus Snorlax now. If you are good in dodging, this is probably the most viable move set out there.

Probably slightly worse than the new moveset set, but that's only based on what I read. No personal experience yet. Probably wait until Gamepress publish their findings.

Regarding Cycle damage, Machamps movesets are distributed as follows:

C / DP (Max)
C / CC (-10%)
C / HS (-20%)
KC / S or CC (-25%)

The difference of KC legacy-movesets to the new Counter-movesets is huge.
Thus, I do not invest in my 2250CP-KC/S Machamp anymore, but i still use him until i have a new one, as it does a really good job against snorlax.

It is simple: Counter is the best move in game, Counter / Dynamic Punch with STAB is the best moveset in Game.

My metrics is cycle damage.

It's better than before, but damage-wise, it would be a weaker version of counter+dynamic punch. For me it's not worth the stardust to invest, invest your stardust on counter+DP or Close Combat with decent IV.
