would like to watch diferent kind of Tanks... yes as it is... not have PLD to be the only tank... why not have a PLD be the typical meat shield Tank against the high Accuracy and AoE(Area of Efect) spammer mobs, but allow MNK to become the evasion/counter striker Tank oriented against High Damage monsters that maybe attack slow and have lack of AoE moves but each move could be deadly to a PLD or anyone else if not evaded, could even make a WAR a new sort of tank oriented to short period time tanking, by having abilities to endure a monster for a short period of time then receive some sort of mitigation if the fight prolonges too long, it would make them the specialist on tank at rush roaming exp parties but not the best at tankin serious monsters like a mega boss from a raid or an avatar and such.

Would like to watch also a "Mage Tank" ... yeah a mage tank... that be specialist on tanking monsters that attack from long distance such like other mages or even archer/bard monsters.

This would be more versatile and would avoid the monopoly of exp parties in a certain point, open gates to new style of gaming. but more importantly break the monotony of always bring the same party setup for everything.
