I can see what your trying to say but most of them points are not tryhards. Admitidly dropshots are tryhard, but when they first started being used they were the SHIZZ. Stuns are usually used by most people who aren;t complete crap at the gae because they are thrown quicker and they explod where yo want, no in the air.
Semtex? Really? they are they best equipment for getting kills but that doesn't make them tryhard.
For UMO w/ SP, it's more the case of UMP with anything. UMP does some serious rape with any Perk setup.
SoH on assault riffles? Again, Really? In SnD they are pretty much the best perk tier 1 for AR.
Ninja on all classes? For the third time, Really? It's the best perk in the game for SnD and it has been since CoD4. It is and will always be massivly used because it is a great advantage to the user as it stops you walking around like some guy who is like 9ft tall like you do when you walk in CoD. If any perk is "tryhard" It's commando, I mean I love the Pro part of commando but EVERYONE knows how stuipid the actual perk is. I raged at that perk on release date :p
But I do agree with you on the headset, however I'm getting my Px21's next week and can't wait.

This is not raelly a :FU: or a :carling: but may of your points are usually what a sensible CoD player does, not a tryhard.
