Is it even possible to solo the deep dungeon?

healer hate rant

Err I don't know if there is any proof that another job has not soloed it also so you might be jumping to conclusions with your healer hate. You'd have to search around the player base to see if anyone soloed it on a different role.

Three posts above yours is a BLM soloing it and they are already on floors 31-40 and they seem to be kicking butt in general and BLM is not a healer....

Just fyi mobs do not spawn in a random level range...each mob type is always the same level (IE: Palace Toads are always level 22, Living Whelk are always level 18, Palace Uragnite are always level 20).

If you are getting mobs 12 levels higher than you then you probably did not kill enough to level up (imo you should be at least level 20 when you enter floors 11-20 and level 33 at least when you challenge the boss at floor 20). The largest level gap I saw was 21-30 floors which seems to have a larger jump in levels compared to 1-20 for an unknown reason. Palace Wivre is level 41 and I was level 33 upon initiation of those floors; 8 level gap. It can still be done though since the BLM a couple posts above has already successfully soloed 21-30.
