ACR was annoying to me, but the MP7 was so awfully balanced that it was basically the breaking point that made the game bad (for me, at least).
 * It had near zero recoil
 * Highest damage at range out of SMG (plus the no recoil making it unbeatable at range, basically)
 * A bigger mag (not a big issue but still adds to CQC and kind of long range)
 * SMG handling (easier CQC ability)
 * SMG firerate (very high CQC ability)

Lets mix this all together: See the problem?
 * Near unbeatable at long range
 * Near unbeatable at close range
