How about limiting how a hat looks like? Most people hat chase to get a hat that actually looks cool. How about making the 1k hat a small mask limiting how big it can be, 5k hat which can be a medium sized hat limiting as well, 10k hat as big as the hat can be made. If you don't like how big the dimensions it should be then why even take towers if you aren't going to enjoy as a fun activity then a reward. If my idea seems stupid then I would rather have 1k removed.
