These new parties arnt fair everyone should get the trophy. Instead of it just being dropped randomly. I've done the parties a few time each and still haven't gotten most of the trophies this is bogus.
They should be dropped more often If everyone got one every time it wouldn't be as special. Besides, if you have a complaint send it to feedback. I'm sure the devs have better things to do than read whiny forums.
I'm not saying you shouldn't post on forums. I'm just saying you have a better chance at getting heard if you send feedback.
