Combine Perks?

[dogbadger]

a more customisable, dare i say rpg-ish element to KF could be nice.
Phaps you could play as one of your existing perks with all that comes with it, but also build up exp. during whilst playing for a secondary perk benefit - that was only present for that game only. Like you say, distributing points and all that.
Go to a new map, and it all resets again.

Idea of combining perks is ridiculously overpowered. Combine sharpie with support and you can carry M14 and crossbow at the same time. Combine commando with demolitions and no stalker will spoil your grenade. Combine medic with berserker and you'll singlehandedly kill Patty.

MORE PERKS - yes!
Combine perks - no!
