Exactly. I think they did a great job with this change.
I think this change actually makes the FAMAS a more viable gun and I think you're going to see a lot less people buying the UMP in lieu of the FAMAS. Previously, the UMP just had too many advantages over the FAMAS. It is $1000 cheaper, has a $600 kill reward and it used to have that headshot potential on armored players. Now that the UMP doesn't have that, the FAMAS actually matches up pretty well with its own advantages. The FAMAS does more armor penetration, it has a much larger effective range, it can wall bang much better and it does a little more tagging.
I think the pro scene was buying the UMP instead of the FAMAS as a pseudo-budget buy because they were still able to massacre fully armored players but with this change, I think the FAMAS becomes more ideal in terms of getting into 1 on 1 fights. No, you don't have the 1 shot headshot potential anymore with the UMP but on CT side, I don't think the UMP matches up well with an AK or Sig anymore. Can you win the fight? Sure but I think its much harder now and I may spring for the FAMAS if my economy allows it just because I wont get fucked on the ranged fights as much.
