I don't think it would be a smart plan to remove it all together just because new players use it as a way to ease themselves into 3s where they might have been only a 2v2 player their before it at least allows an uncomfortable player to slowly get used to the 3v3.
Id even go a step farther and say to make it force Healer double Dps role to help new players get even more used to a real arena. This will for sure make it take longer but i would hope the type of people that are going to Que it Wont mind a longer wait for a more authentic rated 3v3 experience and maybe they would meet team mates in skirmishes that would like to try real Arena after a quick 10 Skirmishes. This would be a great way to meet new team mates without all the pressure of losing rating to test players out.
