I've played with VOIP outfits and squads in beta and launch and while it's a much better experience it doesn't really change my mind about the things that concern me
Some things I'd like to see in PS2:
More ammo types
No, every game that has this ends up the same way: one type is better and everyone uses that. Better to simply make good base ammunition.
Ammo pick up from enemies even in meager amounts
Each faction uses different types of ammunition + that would be catering more to lone wolf gameplay in stead of relying on teamwork (infil hacking enemy terminals, engineers dropping ammo, sunderers)
More tools/kits to play with like different engi turrets, deployable shields, etc
They're going to be doing a pass over each class to expand them more, similar to the TF2 class updates I suppose. Light Assault is first.
More variations in certs
Likely coming with the class updates
Motion sensor and cloak that are worth a damn
+ Infiltrator class that isn't railroaded into Sniper
I don't use infil much but I have been able to use it effectively to compromise gens and turn over lots of important terminals before an assault
Large complex urban or indoor areas instead of spam filled/cramped biodomes and repetitive base/outpost design
In the many, many hours I've spent with the game I haven't had two battles play out in a remotely similar way, except in the horrible biolab chokepoints. Those really need an alternative in future continents.
More fluid infantry combat in terms of movement and gunplay
I've really been enjoying the infantry combat and gunplay after the last few passes over it during beta, only thing I would change is a faster base movement speed
