With the extended AvA break
coming up, there will be an event with the next patch that will buff the SS XP you get from adventures by 300%, as well as the character experience you get from PtP by 300%.
The PtP event is entirely new, and will likely be worth the CP as character XP is difficult to come by at higher levels.
The Adventure XP bonus has been run before, but never as high as 300%! If you have a favourite perm SS, you could consider using Bread to speed up their adventures
and power level them up a bit when this patch hits--that's how some players have managed to reach the SS XP cap of level 127.
