Thing is, Sommers was a fun antagonist.
Having him be simply aura farming material for Zoro is just lame. Same thing could have been accomplished with Killingham.
Would much rather have Sommers vs Sanji still.

Because the thing is, the HKs legit fell flat. The fact that they are mere training tools when Imu himself is in the island facing off Luffy feels even more lame.
HKs flexed on random island giants, some giant teachers, and then Gunko rekt the non-M3 SHs. that's it. Everywhere else they fell flat.
Even GunkImu fell flat.
Wings get scraps. Non-M3 SHs dont even get that.
It's kinda annoying. Why bother having a giant protagonist cast if only the MC matters?
