I completely stopped playing 3vs3 & 4vs4 since December, even though this is what i love to play.
This because of the bug exploits like: relic and ovoo multiplier, spearman damage going across the map, and patches took up to a month on thise game BREAKING exploits.
Drop hacking was the last drop. (No pun. Hehe)
Still a huge fan and playing every day for at least 3 hours, now in 2vs2, and ranked. Going to 500 games soon. 
If i ever need to stop playing 2vs2, or even everything, drop hacks will be the cause.
