There is the Test of Strength gamemode, where you start with a specified amount of money which is enough to buy multiple assaults, but you wont gain money by progressing ranks etc. so when you got no money left and the round is still in progress, you're kinda screwed.
I've never seen that gamemode in public though, maybe coz there are many newbies like you around and it might be a little irritating if they don't go to the forum first...
In Solaris Arena, there is a ranksystem equal to the one from stock crysis
you start as Cadet with 49000 C-bills, wich is enough for several light mechs, some tanks, vtol and the first of three ASF
priceclasses for mechs are:
Light: 49000 - 65000 C-bills
Medium: 58000 - 80000 C-bills
Heavy: 75000 - 100000 C-bills
Assault: 90000 - 150000 C-bills
Tanks cost from 20000 up to 85000
ASF: 25000 - 120000
Vtol: ~ 42000 (there is only one atm)
regarding the roundtime, there are servers where one round lasts up to 120min, and there are other servers which have a ticket based system like the one you know from Battlefield
In general, don't expect it to be like MW4, MWLL is more of a combined arms simulation than a pure mechgame, wich means Battlemechs won't rule the battlefield.
they are however the most powerfull weaponsystems ingame, but this doesn't mean tanks, vtols and ASF can't be a serious threat to you
Whatever, you could read all this ^ and decide whether you like the mod or not, or you could start the game, jump in a Mech and try it yourself...
To be honest, you will need some practice, but once you figured it out, it's great fun!
