Reviewing this lately with someone, I thought it'd be nice adding it into here....
Basically, why not upgrading the kill system in Frontlines and etc? It's a bit kind of sad that it affects you sometimes and you can't achieve a good kill streak or battle fever because most of your kills are 'kill stealed' by bards or other people....
It's just wrong... You lower someone's HP from 90% to 1% and then someone takes that 1% and the kill is for him, it's frustrating and, in my opinion, bad developed....Make it so it is damage based, the one who dealt more damage to the dead target receives the kill.
(If you think this could be exploitable because then someone would do a lot of area damage whole fight and then when you manage to burst someone, you don't get the kill... Then just make it with a counter, so easy as creating object ids for the damage of other players dealt against you, if you don't receive damage in a few seconds, all those ids go to zero again, so basically, only obtains the kill the one that dealt more damage against you in the most recent fight just before you die....)
(Still thinking it's too messy? Here goes a story related example):
You and your friend target a bard of the enemy team and both start attacking him. Your friend deals the double of damage than you, but, you and him don't manage to kill the bard who successfully flees, recovers, and comes back to the battle half of a second later when you and him target him again, this time you deal a bit more of damage than your friend... So what would happen?:
1- If the damage didn't reset when the bard ran away (Bad programmed). The kill would be for your friend, because he managed more damage overall than you counting the damage dealt in first and second encounter.
2- If the damage resets, you get the kill, because the damage of 1st encounter matters not. So in the 2nd encounter, you who made a bit more of damage than your friend, gets the kill.
"And what if you dealt exactly the same damage to someone that the other that also attacked him?" Oh! Do we really care about a 1/10000 of the cases?!... Geez... Well, uhm... Give it to the last one making the hit? Yes, just like now, yes, just in that 1/10000 out of cases.
