"The worst thing you can do in a MOBA is die."
The title is a phrase that a top Youtube video maker on game strategy has said repeatedly.
I don't consider myself an incredibly aggressive player in multiplayer games. I would rather heal or support instead of be a tank or damage dealer. One of the main reasons for this is because, to me, to die is to give your opponents experience, gold, or other bonuses. I won't be the first in to a group fight. But I will shield or heal my teammates. But when it is obvious that the battle cannot be won no matter how much support I give, I'll run away. I consider that to be smart game play. The alternative is letting the enemy kill you. In the case of LoL, death gives the enemy team XP and gold. Not to mention that the longer the game goes, the longer spawn time you have.
I play many games where team members have double digit deaths. The player will dive in to unwinnable fights. Examples would be a jungler trying to gank three enemies alone. An ADC diving in to get a kill but is killed themselves because they've dived too deeply and cannot get out before minions or a turret kill them. A lot of Yasou, Kayn, or Master Yi players will have twelve or thirteen kills. But they'll also have fourteen or more deaths. That, to me, seems incredibly reckless and just not a good way to play. Even when I try to heal people who do this, they are frequently cut down by three or more enemies. And it seems like players just shrug and dive right back in the next time combat avails itself.
I once asked a League player several years ago what an acceptable number of deaths in a game was. I was told that more than four deaths in one game was something to avoid. I always felt that was good advice to follow. However, I'm getting a lot of flack from players lately for not diving in to unwinnable fights or not wracking up a better KDA score. I've been accused of poor play for not having any kills as Soraka. I don't believe people who tell me that. But I am beginning to wonder if a low KDA is a bad thing after all. But I'm pretty sure that if I dive in with abandon, the same people who are upset that I'm not dieing enough will give me grief if I die too much as well.
So, what is acceptable when it comes to deaths and / or aggressive play?
