I will cut anyone who even attempts to change DQ's gameplay. Every single DQ game is the exact same and that's what makes the series great. If you liked the previous games and didn't like DQ11 that means your taste has changed. Time to move on to other JRPGs who constantly change.

The battle system is perfect as it is and is currently the only one of its kind, no need to change it when there are a million other JRPGs who do it differently.

This.  Square Enix seems to have an aversion to traditional JRPG game mechanics and is constantly changing up their other games.  Dragon Quest is the last bastion of old school JRPG gaming.
