None of these new additions sound sensible to me. I'm sure they will be much appreciated by people in general, but I'm not feeling it. Cluttered UI, overload of perks, dual wielding, overkill enabled by default, riot shield acting like ballistic shield, fucking silencers for all guns, heat signature tracking, killstreak options up the wazoo... yeah, this one is for other people. Bummer.
Cluttered UI - Agreed that there is a fuck ton if info being crammed down your throat but idk about cluttered.
Perk Overload - How can you have an overload of perks? So long as they are as balanced and well rounded as the original, is this a big deal? Too much of a good thing is.. a bad thing?
Dual Wielding - I hate the idea of dual wielding but I'll at least see how it works before I care too much about it.
Overkill - It's not enabled by default.
Riot Shield - They have said before that it is a cross between a riot shield and a ballistic shield. Personally why the heck would you want a riot shield in this game? Most of the guns would annihilate it. That said, it seems to work in the game well. You can't fire while being protected by it and I don't think you can carry a good gun with it.
Silencers - Again, I'll have to wait until I actually play the game before I freak out about it. I'm sure putting a suppressor on a sniper rifle will affect the range and damage pretty good.
Heat Signature Tracking - See above.
Killstreaks - You get to customize your killstreaks and there are too many for you? Holy shit who saw all those supply boxes being dropped and didn't get massive erections? Being able to keep your UAV even if you've unlocked a higher killstreak award? Oh snap. Shit is going to be nuts. So much customization and strategy.
