Alright, here it is folks. This is the BIGGEST requirement I ask of you. So get ready...
Play the class you want.
That's it. Really... Well, sorta...
No one is ever going to force you to play a class you don't want to for an extended period of time. We might need you to go engi to repair a generator for 5 min, or medic to revive some people when we lose a sundy, but thats it.
I want players to play their favorite class and get good... A person who is great with a HA overall can beat an INF at long range if that INF tries to play every class. [ex. I play HA and I can take out INF no problem if I play it safe]
I want people to chose a class and stick to it. One primary and one secondary would be good. I want people to be able to switch here and there per situation. Overall, focus on one class, get two load-outs for different situations, and have a secondary class for whatever's left.
I play HA as a primary with a close-combat loadout... Gauss SAW S with softpoint ammo, 3.4LACO scope, rockets, default nades, resist shield, nanoweave, etc...
my second loadout swaps high velocity ammo for soft point and i use the hawk missiles and anti-tank nades... this is my recon load-out
I aim to have an inf build with the Longshot for sniping at super far ranges when defending.
I don't play anything else unless I HAVE to... it works. I want everyone to do the same.
I know a lot of fairly 'optimal' setups for each class, if you want versatility within a given class, just ask!
Overall, pick it and stick it. Ask questions. and as always HAVE FUN!
