I dont really like the idea of locked classes because it kills some of the fun factor when you know that there is only certain combinations you can do.

I think simply restricting the number of certs (lets say to 20) would be more than sufficent to force people to choose what they want, and what they must do without.

Now I think another way you could go about doing this is to make 3 slots for perks (ala Call of duty style) which make it so that your character has some sort of niche to it without instantly being OP.

Some of these perks would be obvious (faster foot speed, faster reload, more resitance to damage, faster rate of fire, more inventory space, faster healing, faster repair, faster vehicle speed, more vehicle health, etc etc etc).

The point would be to make sure that their were a ton of possiblities, but only like 3 could be selected. That way someone could greatly enhance their "role" by selecting certain perks without suddenly becoming good at everything.

Of course you would want to make sure these were only things you could implement at the sanc (to keep people from rotating it all the time) and you would want a cooldown like on the certs for rotation (to keep ppl from becoming the jack of all trades guy).

Anyway, I think thats an interesting solution that would add more dynamic and character strategy without making veterans OP and at the same time help suppress the "jack-of-all-trades" team killing attitude.
