Do you mean Jake or me?
Mechs with wheel? Oh, you mean tanks.
If me, I'm quite sure you understood the thing wrong. By "wheels" I pointed out there were "Leg parts" with wheels/palette like in picture.
e.g. against a legged opponent, the first attach might knock them back to the edge of your attack range, so you can make a second attack, but against a wheeled opponent, the first attack would knock them out of your range, so you lose the second attack.
If you read the values again, I suggested to have the Legged ones get -1 KB range. Didn't say "let wheeled ones get +1 KB range". KB values in the game are greatly increased if you compare how it was some weeks ago. So I suggested shaving 1 KB from 2-4 KB weapons for Legs.
