Here's an idea! Fix the issue where a game abruptly goes to the "Waiting on Server" screen before returning to main menu! This is ABSOLUTELY unacceptable for a game of this caliber! It's the reason I quit spending money because I frequently get a loss in ranked gameplay due to this stupid "Waiting on Server" bug/issue! How about instead of pumping out new cards and other income generation sources, maybe try fixing this bug because it's been happening for years and for me has gotten far worse recently, since the DFT Alchemy release. I've had 6 losses in ranked play in under 30min, with 4 in a row due to abruptly going back to "Waiting for Server"!
Please fix, I know a lot of others are experiencing this, just check Reddit!
