I just got done dredging through the oh so pleasant April Fools "prank" you guys decided to grace me with this year. If the tone of that sentence didn't alert you to the fact that i'm not happy then let me spell it out for you I-M-N-O-T-H-A-P-P-Y. All I wanted to do was get some practice games in before I went to bed and instead I get thrown into a game where I am led to believe the enemy team are all bots despite the fact that I wanted to do a normal draft and to top it all off i'm told that I can't even leave the game because leaver buster is still being enforced. To say that my team and I were pissed would be an understatement. Although I will admit I was far more upset than anyone else on the team the general mood was unpleasant. I just wanted to open mid and end the game but I played it out with as little effort as possible because my team wanted to try to win. So instead of pulling some amazing prank you instead ruined the experience of thousands of players like my team and I who mindlessly wasted half an hour shoving lanes wishing we could just play a normal fucking game.
(If you were hellbent on doing an event like this you could have at least made a new SEPARATE que and told players you were testing a new AI and were looking for beta testers so that the people who don't care about stuff like Urf/Aram/One for all/etc could go on playing a regular game of LoL undisturbed. I would have thought after how poorly the draven heads were received you would have figured this out by now)
