MMORPGs similar to final fantasy

I have noticed that a lot of MMORPGs have a very similar combat system to the final fantasy series games such as myth wars and atlantica online especially have have a very similar combat system to the final fantasy one. As well as a lot of new mmos that have came out recently have done the same, perhaps it is becoming a trend amongst mmorpgs since players have taken a liking to the final fantasy combat system. Although this probably doesn't appeal to every mmo player out there.
