Honestly, I've been playing Minecraft since alpha-ish(?) times. I love how far the game has come but from a user experience and technical perspective it is really lackluster. Performance getting worse with every upgrade. Servers are still(!) mostly single-threaded (there are third party servers and clustering/proxy options, but still). Worst offender must be their account security / support. A few months ago I received a notification that my account had a password change requested. Okay, I reset it, change my email, change my password only to find out my Username, which I have had since I first created my account, has been changed to something else. Okay I guess, just ask support to help with this, right? Hell no. Support just gives a canned response along the lines of "we can't help you with this, please wait 30ish days to change you name again". Okay, I got a bit freaked that my beloved accountname would be gone by then, but apparently it's locked for 35(?) days and I have a 5 days grace period where only the previous owner can change back to it. So I wait the 30+ days only to find out I can't change my name back, because my previous name is deemed offensive (it is not, their bad word filter just picks it up because it got "chink" in the middle ("Schinken" being the full accountname). Support was, again, not helpful just telling me "you cant change to that account name right now". I tried several times and only get the same canned response. Thus I was stuck with either the random name that person changed my name to or find something else. Try finding something nice or similiar to a very common german word, especially after a lot of people got to know you under that name for a decade. How and why someone gained access to my account I don't understand. Why a password needs email verification I understand, but why not a username change? This is the worst. Rant over, but seriously. Mojang lost me with this.
