Remember that if a hero had 10+ kills and 0 deaths in 6.81, that's a godlike streak which gave like what, 1250-1500 in just pure bounty gold? I think the gold comeback mechanics are the most exaggerated. The xp is clearly the big one, whether it's bad for the game or not seems to be up for debate still.
I wonder if icefrog is making changes right down to the wire based on starladder, or if the patch is set in stone. The Chinese/Western clash has honestly revealed a lot (Chinese teams handing out lessons xD). Who thought troll would fall off the map by the end of the tournament? QoP pretty much 100% first ban? All these obscure heroes like Sven, Gyro, and WR coming out of nowhere and crushing games? Lots of new emerging trends, and plenty of outgoing trends.
Just goes to show that no matter the patch, dota is very often a self-correcting game. The meta will always shift on it's own (sometimes sluggishly--it does need a nudge as pro's get lazy), especially at LAN's. Just a result of the counter and counter-play balancing philosophy that dota operates on, and that icefrog nerfs/buffs around.
