I'm noticing people still complaining about the HE grenades and Equipment and I'm sorry but you guys mention these things as if they happen to you EVERY single game which just cannot be possible. I played tons of matches yesterday and didn't have anyone overusing the HE Grenade Launcher and resupplying (like some have stated), nor have I had issues with equipment usages (I used to before when unskilled gamers were exploiting the Private Lobby Weapons Glitch). I am one of the Engineers who will trash you with the Sentry and that's because I'm smart enough to put it in the right positions. It's not overpowered as I've been killed numerous times just trying to deploy the **** thing (LOL) and when the other side has host advantage it takes your Sentry Gun LONGER to kill someone. What's worse is when Ubisoft listens to players who don't play this game as it was designed or like to play "lone-wolf" style (aka, the COD Fanboys and I say this because they are the only ones who run in a straight line as COD has taught them to do), then it in turn f*cks the game up for the rest of us. You had kids crying about the data hacking, now the field computer is slower when hacking someone (now they're complaining about Data Hack looping). Others cried and wailed about the n00b tube, and now that it has changed, they're STILL crying about it! Absolute insanity. There are counters for some of your problems and I'll be happy to state them (your other issues have some very good points such as non-fixes for map exploits and not getting proper points for using your equipment the way you're supposed to):

HE Grande Launcher: Press Down on the D-pad to call for help, or better yet, plug in your HEADSET and TALK TO YOUR TEAM! (I have rallied the troops on a number of occasions when NO ONE in the room was saying a word. All you have to do is speak up and people will follow) Note: This won't happen all the time but when you have people who share a common goal ie: a win, this should work in your favor..

Sentry Guns: Like others said, use an EMP. Boom, problem solved.

HVT is a GREAT objective as it focuses HEAVILY on teamwork. (I managed to push as an HVT INTO enemy territory as the objective was in their spawn (and kill 4 people for a total of over 5000XP and because I was COMMUNICATING with my team, they gave me cover and set up a perimeter perfectly which gave me enough time to cap the obj.) Again, if you're not saying anything no one else will. Sometimes you have to be the ballsy one and initiate communication. One game I actually became the HVT 3 times back to back to back. Lmfao.
