I enjoy PVP and have done so since s1.
I'm not a great player, but i've always managed to play at a competitive level, usually at around a 2200-2300 level across 3 toons (post BC).
What does this have to do with this whole 'MMR Exploit'? Well i'm 100% sure there are thousands of players out there, just like me, that didnt simply get their 2200 achs, t2 gear etc handed to them through some exploit in a 30min time period.
Upon briefly overviewing the CN and EU ladders, one can easily tell that the game is truly broken. IDC about OP classes, getting dc'd on weird maps, or any of the 'unfairness' that's usually inherent (or has been) in this game for ages - but I DO care when I see SO MANY PEOPLE on decent, respectable servers intentionally abusing a system SET IN PLACE to distinguish the good, from the average, from the bad.
Sorry if this sounds a bit harsh to some people, probably shouldn't care too much. Just figure the more people talk about it the faster it should get fixed.
