When I reached level 50 I did think of saving maps in the mail to collect after cap limit was raised. I actually kept several but when one from October disappeared I just took the loot from the rest. I have mostly done the Island of the Pirates map for its nice loot, the low exp is not an issue now. So although the policy to delete the stored XP doesn't effect me I'm still against the idea.
I'm suprised Blue byte is going to punish its most loyal players, those who not only levelled up to the cap but stayed with the game despite the lack of content for the higher levels. I can understand it takes time to add he extra content but the way XP is awarded too players seems to offer the perfect solution . Deleting the hard earned XP is unreasonable.
