Combine having the highest possible stats for the level with the fact that you sync to a level that's actually a few levels above the level of the content (I believe it's 5 levels above in the case of FATEs), and the result is that level-synced characters are really overpowered. (I actually wish they'd be a bit more stringent in syncing to make synced and on-level players a closer match to each other, but then people would complain that they don't get anything by leveling up / gearing up.)
