it is ridiculous that the people that use zwift the most are not getting credited. Increasing levels is a big motivational tool. This is not a hard fix to increase the level limit. Please do so
Make sure you vote up the existing threads requesting more levels: https://support.zwift.com/hc/en-us/search?utf8=%E2%9C%93&query=Level+25&commit=Search
Maybe we will see other ways to use XP besides leveling up in the future.
My biggest motivator is to get my FTP to 5w/kg. 
I’ve been stuck on level 25 for over a year, makes that feature pretty much pointless now, any official information on if more levels are to be introduced? They should wrap them around again or something like they did on Call Of Duty 4 with prestige levels.
