You're doing it wrong.
I would love a game that actually was based on shooting again.
What you mean no explosives, no launchers, and no killstreaks? Probably wouldn't be very well received since MW2 made a substantial change in attracting gamers to killstreaks and other stuff too.
Only issue with EMP grenades is that it works against players giving a free concussion grenade effect and not just against equipment. That's it. It works through walls? So what. You can wallbang with SMGs and ARs so I don't see an issue with EMP grenades working through walls.
I don't really understand why everybody dislikes the executioner it has it uses (1 shot kill at point blank range) and in most CBQ situations you can usually get the kill (using akimbo). The executioner is fun due to its difficulty it's my second most used weapon (only to the fal) with 983 kills and .98 K/D
