Personally, I think that although brand recognition is important, a stale design is completely unattractive, and turns people away. If the design that a team is using is too old-fashioned, or an eyesore, a redesign can be a breath of fresh air.
This year, some of the members of Team 830 did a draft for a redesign that eventually failed, however if that logo had been much better than our current logo, it would have been good for the team's public image.
