At least in the Capitol Region, many of the teams who did Mecanum drives 2010-2013 had magnificent and beautiful looking drive trains, followed by piecemeal and somewhat functional mechanisms. This tells me that while the Mecanum drive probably works well, the drive team probably had very little practice with using the drive train and mechanisms together. 623 was typically a good example of this, yet in 2014 they pulled it together and found a very lucrative role they could reliably fill, winning them Chesapeake.
It's tough to write off a Mecanum drive just by itself, IMO. It's far better to see how a team uses the Mecanum and how well the robot performs a role relative to other robots that perform the same role.
BTW, to me this wording is as hilarious and ironic as a license plate that says "Epic Fai" - I just may have to change wording in some of my drive train presentations:
