I paused playing PR completely around the time Mumble was introduced, at that time I had severe problems to get it working resulting it to be one of the reasons I paused (many other things in personal life). When I arrived back last week I was more than positively surprised how well you've managed to integrate Mumble to PR - this is awesome! I'm loving it.
The animations of the soldiers from running to firing to dying look smooth and good, the awkward 'jumping and arm-waving ragdoll' seems to be gone.

Everything feels so smooth, that's the word.
The shooting itself has become more accurate, but I'm not sure what to think about this. Sure you hit your targets now, but does this make shooting too easy? The enemy actually drops dead instead of me.
After thinking about this for a while I've come to the conclusion that it's a good thing, makes people move much more carefully avoiding stupid risks since they know running won't save them from getting hit now.
I both love and dislike the rallypoints at the same time. On one side they make it easier for your squad to stay together, give your squad more possibilities to do something if the rest of the team is messing everything up, but on the other hand it reduces the need of FOB's and transport vehicles, making them almost useless and in worst cases can make a friendly/enemy squad just spawn behind your/their lines.
I might also like this purely because rallypoints were how we played it earlier.
The new squad size seems to bring both positive and negative stuff with it. The positive is how well an organized 8-man squad can inflict damage and firepower.
On negative side I noticed today was how it restricts the amount of squads available for creation, resulting in too little of them it seems. The following story and rant is from my first experience with 1.0, which ended up negative and giving bad feelings:
Me and my friend created a squad, but it seemed like nobody wanted to join so as the match started we continued up to a flag with a mission to defend it. Later 3 people from a clan joined and started demanding that my friend would step down from the SL's position to give it to him, which to my friend politely refused. The defensive marker was still on the flag and those were still the orders.
As the game continued the clan kept complaining how we are "2-man squadding" , demanding the SL's position and insulting both of us, even going as far as giving out racist remarks and even telling an admin blatant lies trying to get rid of him. This is not how PR used to be when I played a few years ago.
The whole time they were focusing on this, completely ignoring the orders from the SL that were to defend the flag (which we surprisingly lost when nobody was defending it). At the very end of the game they teamkilled the SL and sprayed their magazines his dead body. I lost my nerve and killed a few of them.
I'm not giving out any names, but I've never witnessed such inflamed cases in PR before, I remember people being friendly. This really ruined my evening, but luckily the next game we found ourselves on the other team in a squad full of friendly and intelligent players who knew what teamwork was. Saved my evening.
It seems people will always have problems playing a defensive role (personally I love it). Earlier you could create your squad and defend a FOB for example, nobody could complain since they could leave and make their own squad, but now with the restricted amount of squads this seems impossible. "If you're defending you are wasting a squad", is pretty much the message I get.
Just my thoughts.
