Attrition is Completely pointless

So like any game of Attrition there are Trolls that will kill themselves to lower the their teams lives count, there are also the bots that suck and are free kills, if you have one weak person on your team you lose. Why didn’t they just add Elimination? at least i could have gotten the final achievement that way. These game type do not work with halo, also Randoms are not people to play this mode with, at the time of this post ive lost over 30 games in a row, 0 wins, and 7 matches lost do to trolls. Please for the love of god 343 quit making game modes where i have to relay on my team mates like this, or at least make a report system to report trolls.
