Wow, how creative of you, Jagex: even more boring exp sellout, just a different skin on the consumed item! Is this literally like celebration lamps, except that it's bonus exp rather than direct exp, so I assume that means you'll be getting even more exp in total as compensation for it not being instant?
In addition to the above, a couple other questions for you, Jagex:
1. What are the actual numbers? As in, how much exp are you supposed to get from these? It's bad enough that you hide the probabilities of landing on the certain prizes, and this is just more obscurity on top of obscurity.
2. What are we supposed to be partying about? Last I checked, April Fools is already over, and Easter is a few weeks from now. Adding more parties to a year makes them less special, which in turn makes them boring.
EDIT: Just remembered that portable Vic is coming later this month, so this seems to be one of those "look guys, we're easing up on the P2W!" promos but which will actually lead up to an even bigger P2W promo. :/
