the heavy hand they had w/ rehgar makes sense in the context of more smaller patches,
This is the best thing about the more frequent patching. They can have something broken like Rehgar's shields or Lili's W bug go in and people can enjoy it (or hate it) for a week and then they can tune it a bit and show real improvement of heroes.
IMO it's hard to get the numbers just-so. By realizing that (A) we wanted more frequent patches and (B) it could actually make their job easier, the game is so much better moving forward IMO.
