Ok so after few more rounds my view has improved. Playing medic was bad idea. Revives don't get rewarded much and guns are weak, plus your health auto heals very quickly so don't really need health packs. Assault on other hand has some nice automatic guns and benefit of mines and c4 mean it's the kit for me. Still don't see the point of those 'special' kits. Just a gimmick which serves no purpose other than to get some 13 yr old camp a spot till they spawn.
