You never played 1v1 vs soviets when they were OP then. 90% of top players thought demos were OP. I haven't heard a single top player complain about schreck blobs recently.
The maxim is not THAT bad. It's semi decent when you use sustained fire vs blobs. It's bad vs spaced squads. I still don't see why demos should get any sort of buff. They can still 1 shot any squad when they're on garrisons. Axis factions don't get that luxury, and only the soviets can do it nondoc. If the arguement is that top players don't use free squad wipe tools because they're situational or lazy it doesn't seem like they should be buffed. If that were the case, "booby traps" should all be buffed because they're rarely used as well.
Shreck blobs are back in 4v4's. If you really doubt this, play some random 4v4's as allied. I see them more often with Pgrens than Pf's. The Pgrens work better than PF's due to their bundle grenade. I've had a lot of MG's decrewed because the Pgrens were still able to close to within grenade range even with the MG firing on them. Standard infantry, even with LMG's, isn't much of a deterrent. Grenades are helpful, but having to pay the side tech costs means puts your armor behind. Assault sections or Shocks do work well. Pack howies or Scotts are the best USF counters. It will be interesting to see what happens when those are nerfed. The boost to short range DPS on rifles might help.
A group of three Pgrens will insta-wipe any standard allied medium. That's only 300 munitions and you can use it over and over. The biggest part of the problem is how cheap shreks have become. Players have complained until the price of shreks is the same as the price of bazooka's or Piats, but you get 50% more damage and 50% more penetration so that even heavies are at risk to shrek blobs. The price should be raised to at least 70, maybe 75, and the drop rate put to .33.
I don't agree with bringing back demo's in their old form. It was more toxic to gameplay than snipers. I wish they would have made demo's detectable by infantry at 20-30 range instead of the white circle. Demo's plus a regular mine used to work as the Soviet version of the teller and were really good for preventing Panther dives.
