I agree that the events mask vanitys shouldnt be so rare but all the other vanitys should stay the way they are. Vanitys like the pet, gamers, manic are here to stay forever they should be very rare.
If all the vanities were easily attainable then people would complain that the games boring nothing to do. It does suck when a new player thats gottan a rare vanity after 5k kills to your 50k but drops randome and thats how it works. We should just congratulate and be happy for them not overly jelouse.
