Holidaiz Repetitive?

Ok, they’re fun.  They break up the same old day to day.  They take us  to places we don’t ordinarily go, and get us to view content we don’t otherwise see.  But sometimes I get the feeling that it is repetitive.  Maybe that’s because I play multiple characters, but maybe because it’s the same thing every year.  Like running kegs back and forth, or cleaning up stink bombs.  No offense, but couldn’t they add something new each year, instead of just upgrading the boss to a higher level?  Change something maybe?  I guess the assumption is basically that you’ll do it once or twice and then be done.  I guess they do add a new holiday from time to time, but I dunno.  Just sometimes seems to be repetitive.
