I disagree on everything.
...The cutter nerfs were not, because ODSTs were so easily counterable and only came up at best, once every 3 minutes. They were absolutely useless against Banished because of shields, and after early game against UNSC they weren't worth much either. Raid did not make UNSC useless, as all of the other leaders maintaned powers that would allow them to win engagements.
The only thing Cutter had going for him was early game map control and hit and run tactics. All of the Banished had advantages over Cutter, and Kinsano and Jerome could also hold their own against him. With Scout vehicles being so OP, Raid wasn't nearly as effective as it could have been. Again, the best Cutters were forced to MICRO, which is something that should be rewarded, not nerfed. This is why Atriox is still one of the stronger leaders despite the season to season nerfs, they were all minor and he can still just ball up and run through opponents. Why they hammered Cutter when he was fine, is beyond me.
They replaced him with Forge, who is incredibly OP. In addition, there are still only 2 leaders worth picking for UNSC, Forge and Serina, with the rest being virtually useless.
Every good Cutter just circled your bases one by one until you were done. Banished couldn't do -Yoink- even with rangers. And that's another reason why every other UNSC was crap against Banished, because rangers rendered them useless. Cutter was the only one who could really screw Banished because his infantry was as fast as a damn Chopper.
And in UNSC vs UNSC no leader could stand up against cutter because even if you won the fights he could just ODST snipe your generators because UNSC don't have shields.
Speed is incredibly strong and valuable in this game because units can shoot and move. Take a game like Starcraft for example where units have to come to a full stop to be able to shoot. If that was the case in HW2 then cutter would have been more balanced.
It is time to move on and acknowledge that Cutter raid and ODST were broken. And they haven't replaced him as in replaced on purpose with Forge. That makes no sense. Once Forge and Serina get nerfed we will be able to make accurate comments on the meta.
I won't say whether the nerf was too hard or not because we cannot say for sure in the current state, but a nerf was needed no question about it, so... Let's just wait and insta lock Forge in the mean time.
Rangers absolutely ran through Cutter. In fact, the Banshee, Ranger, Reaver combo ran through Cutter like a warm knife through Butter.
So when I said they replaced him, I didn't mean that they were like "Oh well now we need a new OP character to replace the old one" lol. I meant that Forge and Serina (who are obviously much more powerful than Cutter ever was), replaced the UNSC meta. Speed is important, and it was the only thing that Cutter had going for him. You disagree on everything, but don't seem to have the experience I do in playing with him. ODSTs nor Raid were broken, and he was clearly over nerfed. If anything, they should have just left him alone, and there would be more parity between UNSC leaders.
You seem content with the fact that there are only ever 2 viable UNSC leaders, where as all of the Banished is viable. Had they not nerfed Cutter, you would have Jerome (to an extent), Cutter (kind of but he's not nearly as strong as Banished or Serina/Forge), Serina, and Forge. As of now, they absolutely nerfed Cutter into the ground, making him useless.
If you can't see that, then I don't know what to tell you. There was no reason to nerf Cutter in the current meta, and if they were, there should have been small, slight changes. He is now useless, is that what you wanted? This is not how you balance games.
EDIT: I forgot to mention, because scout units are so OP, Cutter's raid really wasn't as useful early game as it should have been. That's why Banished always had the advantage over him, Choppers/Ghosts for map control, T2, Spam Rangers, profit.
