The things you describe are only bad in your opinion.
Only the unskilled played aimlessly lobbed grenades around, as at a certain point the community came up up skilled ways to play the game, and any player worth his salt threw the errant grenades away. Whole tutorials where created to demostrate how to effectively throw grenades. And the cluster grenade was a thing of beauty. No more could teams bunch up and control a power spot all game. They were forced to move. I can't say the same for this game as I have seen it happen numerous times. Heck I myself am guilty of it. I'll gladly take the grenade spam with skilled grenade gameplay over this alternative, in which if nobody is running up behind you, you can endlessly be engaged in gun battles where it's the two of you sticking you head out and then back down again. there's fewer options until someone opens their in game store (provided they have enough money) ripped unabashedly from TLOU.
Look, The game is good, But UC3 was better. It was more action and excitement driven. versus this games much slower (no sprint, crawling on the ground) and straight forward approach.
Punishing winning teams by giving opponents double damage is a bad mechanic. That's not just an opinion. Power Plays existed to keep games close. In UC3, you needed to rely on Power Plays. In UC4, you need to rely on teamwork. One is an artificial means of creating tension, the other requires player input and organization.
It is much more rewarding to make a comeback in UC4, knowing that you did so because your team got together and stayed incredibly focused. I've played many UC4 games already where I was down by as much as 15-20 points, only for our team to come together and mount a comeback. This is incredibly rewarding. In UC3, you rely on power plays that give losing teams advantages for falling behind.
Kickbacks that let you instantly explode grenades for cheap, and boosters like fleet foot that could be upgraded at insanely unbalanced levels are also poor and unbalanced. Loadout points are a superior implementation. Something "ripped" from LoU (which was ripped from COD), but that doesn't make it a bad thing.
Uncharted 3 is vastly inferior as a core game. It doesnt matter if unskilled players spammed grenades. Everybody spammed them. If you were better at spamming than others, then that's great. But if you're going to just respawn with your grenades all back, spamming is always encouraged, and with spam, you get a lot of lucky kills.
There's no thoughtfulness to that, or to rolling right before you die and dropping a grenade like it was COD4 martyrdom. UC4's approach is what I prefer, and I don't see how commenting that it lacks UC3's grenade availability is considered a bad thing. It's different, and in my opinion, better for it.
If you think cluster grenades are a thing of beauty for clearing rooms, try out the El Dorado. It's just as effective, without being as powerful.
UC4 is hardly slower. I dont see how you can say that. There is a ton of chaos and action with managing revives, healing, and finishing off enemies.
