Quotes from the D3 Dev AMA

[Ruvanal]

I'm wondering if they're going to be doing League of Legends/Dota2 type balancing (This is under used, give it a 5% internal boost and see if people use it), or a Diablo 2 style balancing (FOTM TIME!).

Frag this is Blizzard. Of course it is going to be FOTM TIME!. I have seen too many times that their developers are working on the basis of 'do not do little piddly 5-10% changes to adjust things since it can take too long to get to good level, do x2 and x4 adjustments to really see the effect of what they have done. Then followed by a number of patches doing a cycle of super buffing and heavy nerfing, they will start to get to balanced point. Then its time for a super patch or expansion to change a bunch of the game mechanics so it all has to start over again.
