I couldn't care less about "cheating" in PvE content, the only person you're cheating is yourself.

However, in PvP you are actively screwing with someone else's game and chance to win fairly, this is especially bad with things like exclusive Top 100 prizes and such. I don't think anti-cheat software is the answer, I think SE should just have dedicated PvP mods constantly in the mode watching the battle logs and looking for suspicious activity like players who are magically able to toss Ninja LB on anyone the nanosecond their HP hits that threshold, or players who just happen to CC anyone in range the very moment they are in range every time. It's like playing against the button-reading Mortal Kombat 2 AI sometimes.
