Again, said this several times, I know cheaters exist although I have yet to see one (just my experience). However, how often are good players going to be reported just because they have 275 kills and 76,890 damage on their banner? Not jumping on you specifically but you are like the 15th comment Ive seen about someone seeing an impressive banner and immediately saying "hackssssssss"
This is a perfect description of the other major problem involving cheaters. The fact that loads of people start point fingers without having any substance backing up their arguement. In all the games I've played I can say I saw two cheaters for sure and they are very easy to spot since you can spectate after they kill you.
The banner doesn't say a lot, but do they move slow & newbish? At the same time do they seem to know where all enemies are? Laser them down with snap-aim?
Easy to spot.
FPS will have cheaters, weither it's free or not.
The only long standing and populair FPS are those that are competitive.
Problem for EA: how do they make this somewhat competitive (eg ranked queue's) without having it get overloaded with cheaters?
Better report options and a team that actually review these would be a start.
