And events like that should have never made it into MMOs. They were fine in shooters, etc, since the game wasn’t about achieving things; but almost purely about gameplay. Why would I farm X or grind Y if I know it’ll be twice as quick to do it when the weekend comes up?
As for your given examples, they’d be very unfair to particular classes/characters. Due to their large weapon pool, warriors would benefit more than engineers; for example.
It’s a fun idea, but it’s just a novelty. It’s intended as a helping hand or an incentive, but it just turns into a massive grindfest during those periods to make the most of it. I remember on a certain other MMO that gave into these events (and various other bad practices), the months leading up to a double experience weekend saw the economy be completely and utterly destroyed by hoarders, speculators and manipulators and players just gathered all the resources they’d need to make the most of the experience boost. I really don’t want to see that here as well.
