It adds up though, I mean I think the event is pretty funny in itself, I don't mind people enjoying their selves but its been pretty inconveniencing to me.
All I really do is que for PVP and so obviously I'm going to lose my vaccination (because it perishes when you die) and its unavoidable since they're infected people que'ing that blow up on you when you kill them.
Essentially, I've had to buy a new vaccine after every warzone. I wouldn't mind if the vaccinations stuck after death, but this is just a -tad- inconvenient. Its also very random, I saw a guy about to score in huttball and didn't get to because he EXPLODED in the end zone, thankfully he was on the other team .
