This is my opinion. Please respect that.
First, for those like me that pay tier and have to already pay to be premium to do so this "raise" hits us hard. SL has already raised the "processing fees" earlier this year up to 2.5%, now they are raising it to 5%. When will these "benefit" most of the SL premium users instead of hitting us the hardest?! If this keeps going, I may end up going back to basic, stop paying tier and premium then who benefits? SL? I think that is going to be the case for the most part. I hated "renting" from other landowners which is why I chose to purchase my own land.
Now, whether you are a premium player or not, SL raises fees all across the board. Buying or Selling Linden, premiums, processing fees... it is becoming very expensive!
Thank you for listening to my thought :)
