Deep Dungeon rankings should not reset when switching servers

[SuperZay]

What's the reason behind this? It's not PvP rankings where every datacenter has different players, it should not matter if I did 150 floors solo on Cerberus or Ragnarok or other server, personal records should permanently remain in players data because they are not affected by anything on a new server.
Right now, because of temporary nature of Palace of the Dead leaderboard, it doesnt give me much reason to try climbing on other jobs, because all that hard and time consuming work will be zero reset if I'll switch server.

If I may ask... why would this be an issue... unless you're actually planning to either change server already (in which case, just switch before doing PotD)... or you're doing or planning to do something that might make you want to change server...

I don't really see the issue to be honest, it's not like if serverhopping is a core feature to the game XD
