If those changes happen I will uninstall the game, I love mtg and have played for more than 15 years now, I have my Arena account since the closed beta and have convinced multiple of my friends to ditch other tcg's for Arena. I play exclusively historic, as I prefer non rotating formats, a long time ago you promised to implement Pioneer onto the client, but you lied about it, now you plan to terminate the only eternal format available without ant consideration to your player-base. If Alchemy affect historic without any news about pioneer, in the 8th I will log off after completing my dailies, something that I have done everyday for the past two years, to never login again.
