To be honest, I'm surprised SE doesn't do limited time bonus campaigns like other MMOs. Like 2x EXP, or 2x Item drop campaigns etc. Maybe the code doesn't support it (which is why they release equipment with EXP bonuses maybe?). That said, if they were able, it would be cool to run a 7 day 2x EXP, 2x Tome event where daily roulettes give 2x EXP/tomes for limited time (maybe coincide with temporary increased tome cap)
