Altruism is a real world demonstration of this . Are you indicating that you believe in materialism ? Because everything thus far from our conversation would seem to suggest so . <| sep |> there are quite a few reasons for people to quit and some are logical , some are not . if you are playing on casual or normal , then people leaving are just because they dont like what they see , how people play or the map . if its on hardcore or insane , the following are mainly the reasons 1 . majority of the time they quit right at the beginning because they dont like the team or map they see . in the lobby they cant really leave unless shutting down the game completely . team make up and the map is a very important , for team you need at least 1 engineer and 1 scout , the scout is capable of doubling the amount of power you get during the wave , and also again giving another bonus of 1050 % bonus power when depositing it , getting as much power asap is very important in order to upgrade the fabricator . an engineer is a must have because they can purchase fortifications at a discount and also get improved health on those fortifications as well . the more you have the better your base will be . also they spawn in with the repair tool which is used to repair and refill ammo to all fortifications , it would cost your team 5 , 000 to buy one and its not worth it , not to mention if they die while holding one , you lose it . where as the engineer will respawn with a new one . as mentioned earlier map choice could also be a reason , there are some maps which are designed fairly well for horde , and some that are designed extremely hard for horde . many people dont like maps like harbor , lift , or forge because people like to have enemies spawn at one end and let them funnel in . these maps provide little cover at the spawn points and are very hard to defend , so many people just bounce out if they get stuck with this . 2 . the next reason people might leave is people not playing their roles . for example when everyone races to pick up power when they have a scout on the team , this will most likely make the scout leave because they arent able to do their job and thus becomes a useless part of the team . or people building fortifications willy nilly wasting precious power when the engineer could do it much more efficiently , or seeing someone spend power on a repair tool and repairing things needlessly . this is a team game and if the people dont play as a team , they wont want to stick around for a failing game . 3 . The bounties . because you can only have 1 bounty equipped and they give no incentive to finish the 50 rounds , people just leave once they ' ve completed it because its just more efficient and faster to level up doing this . especially when they have no confidence in their teammates to go to wave 50 . 4 . and the last thing is simply they have no faith in the team . when people just willy nilly be running around like idiots and not sticking with each other as a team in a single base , it makes things much harder and majority of the time they end up getting put down with no one to help them out . again this is a team game and thus its always best to stick together behind fortifications and using the tools you have . only the first 2 waves of each set it would be acceptable to be out there since sheppards and trackers are fairly easy to take on even on waves 31 and 41 . so yea there are plenty of reasons why people leave and since there are a ton of ignorant people out there who arent willing to learn to play properly , it has made the community pretty toxic and you ' ll have a tough time finding a decent team in a random pug . better off start making a list of friends to play with and start doing private matches when you can .
