I got lagacy, my sub is cheaper.
I pay for 1 extra retainer.
I don't have invatory issue because I sell stuff my 3 retainers, I log and make sure 20 items on retainer. before logging off I make sure they are full again. I undercut my 5%
I do agree with some of the OP issues.
But Not have extra retainers isn't effecting my enjoyment.
However there are things I would gladly pay extra for like a HD texture pack.
SE is a publicly traded company which means it's in it to make money, and answers to it share holders. This means when I logged in to day and did Eureka, and saw 5 people with the $24 mount that came out today. I was like they got to much money but if that's what they want to spend it on that's there choice.
I use patreon to support some project and content creators which is no difference really. I pay a little extra and get perks.
