-Exp rings don't work at all (That sucks)
-Lvl sync works but is capped at a 20 lvl difference (That's doable)
-BLM can sleep all undead mobs (Oh sweet!!)
-elementals have no specific resistance (Good for crystal farming!!)
-bcnm and ksnm are currently disabled. There are Wyvern 'NM' in the open world that cap you to bcnm fights. They aggro by sight so be careful (No me gusta)
-TOAU works kind of but all the mobs are lvl 99 (I do not like this, but I can do without Treasures)
-the actual mp cost of spells are higher then what is listed in the spell menu (Sucks for BLM/RDM/WHM. Even more for BST/WHM

)
-Monomi ichi does not work (Alchemists must love this when selling Silent Oils)
-Tier II enspells do not work but people will sell you them (NPCS) - (Lame)
-There is a chocobo circuit that connects the three starter cities. You must be lvl 10 and have 500 gil to enter. It also acts as a bazaar oasis. - (This, is awesome. Only problem is that I only got 10gil atm. Need to kill more and sell crystals! LOL )
