Some reasons for a team death match server
I totally understand that a developer doesnt want to waste time with a product when he has doubts that this product will be a success.
I will present the most important advantages of a team death match server. Hopefully a developer takes some time to read and think about it.
I dont expect a complicated money and xp system.
Players go to duel server not for money or xp. They go there to improve their skill, or simply because they like some one on one action.
Same would be with team death match server. Players would play there because they want to have some fun.
A) So, now why is team death match more fun than battle?
1) No annoying waiting time. You log in, you spawn, you are in the action, you have some fun. Simple.
2) More bravehearts. In battle, at least in EU1, everyone is some sort of a coward. Scared of dying early (and having to wait for several minutes) for the next round, they hide, camp, run, and if they go in combat, then only when they have more numbers on their side. If they see the team will lose, even more hiding and try to get the valor (besides, valor should be for valiant warriors only, not for some coward hiding/ camping with a crossbow)
3) Less rage, anger, insults
Most of the hate in-game (in my opinion) is based on frustration. Players are frustrated in real-life, want to relax and play a videogame, spawn and get raped by a lancer. Next round, they get one-shotted by a ranger. Some start insulting in-game chat, others rage-quit, and rage on the forums.
On a team death match server the people just play the game. You die, and you immediately respawn. There is no time to argue with anyone.
B) So, now why is team death match more fun than siege, capture the flags, .....
Well, simple. Siege, capture the flags and similiar game types dont make any sense. It doesnt matter how many you kill or how often you die. Just noob-rush to a certain point and eventually hold it for some time.
Team Death Match is, of course, somewhat beginner-friendly, but thats not a problem, is it? From what I see in native, players try to give their best in team death match, try to improve their personal skill. Noone wants to be the guy who brings the team down.
