Alright so I played a lot after the patch, I think I can give a solid opinion now.
First of all that guy that keeps complaining about the game here, I think its LTFC? Don't get me wrong, I agree with you in all of those complains, but you are a fine example for the things that have changed.
You will be happier now, looks like they have listened to you.
Vehicles are much more vulnerable now, stingers and javelins are actually powerful, Choppers also take more damage while Jets are a bit faster, which make it a bit harder to control.
That Repair tool is slooooow now, you cant cheese in the back of the tank unless its 3 guys. A 20% tank for example takes a whole bottle and doesn't get to 100%.
Now the matchmaking and joining friends its a lot better, I always end up in my friends squad or team, but that has a bad effect since there are always those 'clan teams' against messed up teams.
The rent a server thing its great, you can customize a lot of things, kick people, change tickets, choose maps etc. Check that match with 2000 tickets for each side
http://battlelog.battlefield.com/bf3/battlereport/show/38363569/4/266318909/ tons of kills on both sides, the match was long, we dominated than got dominated than it changed again, really amazing experience.
Now the weapons is the part I don't like, I get it but still don't like.
Recoil is so much bigger now, and the accessories seems to have a more negative effect, I'm hating them all but the foregrip and suppressor. And all you see is rifles with suppressor now, its the new USAS.
All weapons, except the Snipers, seems to take more bullets to kill and people that play on short range are playing much better, those mid range kills are hard now, and Battlefield ain't short ranged, so that is frustrating.
If you try to get someone from midrange like before, you will only catch attention, hence the loads of suppressors. Its better to get close first before killing.
Finally the frag slug sucks now, people that shot me from more than 100m were taking 10 to 30% tops. Not to mention nobody is using it now.
I recommend those that gave the game up to try again.
