Every expirienced player know that the easiest way to farm points - take some huge caliber and kill with splash dmg 10+ enemies per shot(bomb/2 rockets)
Also there are some average ways to farm: AT guns, tank MG, LMG/HMG and mortar.
But all those methods need either expirience to know where the enemy will be for sure or friendly correct marking near the enemy.
And right now marking is somewhere between coma and death. Because if someone mark the enemies for you - you will harvest points, meanwhile this friendly person will be just a passive watcher.
(exept 15 points for marked tank being killed, meanwhile single enemy kill performed with your AT/AA guns or LMG/HMG by your ally will give you 18 points XD)
I think we need to add a bounty per each enemy killed near the mark within some distance let’s say 4-5 points per enemy.
Yes, all other 9 teammembers could mark the same 10 enemies and (once friendly tank will kill them) get 50 expirience each without a single shot from them. But this will worth it, since cooperation should be rewarded!
Yes, this will create some perfomance consumption but, I think DF have nice progammers those will be able to find a super effective algorithm to reduce this consumption as much as possible
