About the buffs and subsequent nerfs to ardent censor and mikael's
You know, I'm a little surprised riot let those items into the wild without at least making them unique to begin with. TBH, I thought they were on the page that healing is toxic so the fact they didn't even have a precaution in place on the changes seems off to me. Also, they should have known that if it was possible to exploit, the players would try it.
So Riot, how did the healing boosts get released in the first place without being unique? That seems like a balance safety process (or two) had to have failed.
As a second question, is having only master+ QA members an issue? At that ELO are players too conservative with things like builds and are your internal guys unwilling to experiment or "troll" by seeing what happens if you stack +60% healing on someone like Soraka or Sona? If no one brought that up as an issue maybe you guys need to double check how you review things.
