They make it hard for anyone to really get ahead. It seems every chest is purposely aimed at cards I don't use, so I'm never leveling up anything that would defeat the people I'm being matched with, yet those people have such upgraded stuff that I don't stand a chance. Scarab's laser is pretty unfair to play against, especially when paired with the spiderlings and/or laser tank. They've also made it nearly impossible to get new characters without spending ridiculous amounts of actual money.
