Both issues are mentioned in the latest patch notes. That is why can be sure about the devs looking in to this issue. So i expect some changes in the near future to deal with both problems. Just read the patch notes. Problem 1 is mentioned under ongoing investigations. Problem 2 is mentioned under the new EW ladder and the issues with TG rating (this is not a clear reference to smurfing, but i am pretty sure they meant the issues with smurfing).
For Problem 1:
I explained my view multiple times in that thread.
For Problem 2:
The old calculation were terrible. I made this thread about the old calculation and i am glad it changed. Previous TG elo was meaningless. Now it is exploitable by smurfs. I prefer the second, but they devs have to deal with the smurfs. Not sure if that is also discussed in this thread as well, so i link for some other threads about the smurfing issue as well:
See for example post 3 which is posted by me.
This is another thread in which is probably share my ideas.
Just do a quick search and you probably will fine more threads about this subject in which i shared my opinion.
