I think it would be interesting if you were given some sort of bonus for getting level four in two classes. The bonus would depend on which class you got to first and which one you are when you get to the lvl 4 in the other. They would only be useable in the class you got to lvl 4 in second.
Some examples:
(1st) Lvl 4 Signals + (2nd) Lvl 4 Medic = Health kits give a clip of ammo
(1st) Lvl 4 Medic + (2nd) Lvl 4 Covert Ops = Satchel charges look like medkits
(1st) Lvl 4 Medic + (2nd) Lvl 4 Heavy Weapons = Regenerating health
The classes with the (1st) next to them would be the classes you started out in, and got to level four in that specific class’ skill. And the (2nd) is for the class that you got to level four in second. The skill would benefit the 2nd class (the one you would be when you gain the skill). And they could make it a server option and all…
Got any more ideas for bonuses than add 'em. Don’t like my idea, tell me…
