I find it quite acceptable now Pat, it's actually not too bad once you get used to it. Here are a few pointers in case they help:
To redeploy:
Touchpad to bring up map ---> Square to redeploy ---> then R1 / L1 to move between spawn areas. If a certain area has more than one spawn point on it (ie. a spawn room and a few sunderers) they'll all appear on the left hand side. Up and down with the D-pad will scroll between them. R2 and L2 will zoom in and out of the map so you can see where you are in the bigger scheme of things.
A few other tips re. redeploying:
Your last position will be marked on the map with an orange triangle, so you can orientate yourself and spawn where you want to.
When you zoom out, only a portion of the map will be highlighted. The bits around it however are still translucent and still live, so you can also see what's what in the surrounding areas.
To warp to a different continent:
Touchpad to bring up map ---> Square to redeploy ---> Square to warp which is a bit confusing. It doesn't actually warp anywhere, what it does is instantly highlight the warpgate on the continent you're on so you can redeploy there instantly and then use the warpgate to warp to another continent. The Square button should say "Warpgate" rather than Warp as it confuses lots of people.
A few other things:
I have proximity chat turned off. It's no secret that I cannot stand hearing shit in the background of other players, let alone randoms. I was playing the other day and someone in my squad had his microphone on and was getting yelled at by mom. I could also hear a toddler in the background and a washing machine. I muted him and later on I came across another one playing some crap techno music so I just turned off proximity chat altogether. Massive jump to framerates too. Luckily I mainly play medic and injured / dead people have icons above their heads so I know where to go, there's no need to listen to other players and I find the game considerably more entertaining like this.
As for the useless players, remember that this is a brand new F2P game, so anyone can play it, even kids without PS+, and that brings the obvious with it. Once it settles down a bit I'm sure the players will get bored and leave or get better if they enjoy the game. In the mean time, I either hook up with Lee and Stretch, or roll solo and simply ignore whatever everyone else is doing. Saves a lot of teamkills too.
One more thing, on foot you're extremely squishy, especially with no suit upgrades. This is a bad move from the devs in my opinion but it does help weed out the CoD kiddies. You need to think in this game to be successful. Situational awareness is king here. Learn your minimap, learn the symbols and emblems and keep an eye on where allies are, and work around it. Crispy had an awful night the other night because he wasn't aware of where he was spawning, where the bad guys were, where allies were, nothing. He simply spawned and ran out guns blazing and died. Again and again and again. A good idea is to roll with a Sunderer if you can. Find a good spot for it and deploy it so your team can spawn on it. You'll be making a huge difference for your team and getting tons of XP, as Stretch found out the other night, he couldn't believe how much XP he was getting. It's literally a non-stop stream.
//Apologies if this is standard practice for you, but with the steep learning curve loads of people are discouraged very quickly so I try to be as thorough as possible as to get more players in to the game!
