They can take the targeting system as is, make switching the modes more user friendly, good way like they did with the controller zoom feature, Hold auto-run + D pad up)

In addition add the features from FF11 <stnpc> <stpc> these would do the same thing, with the /assist function most all the targeting problems would be covered.

To make the monster that is targeted more visible can highlight the name, or small arrow above the name itself, the addition of a circle under the monster for identifying as well above would be good or bad depending on how many monsters are being fought or size of the monster.

So far the targeting system works fairly well, only issues come when trying to scroll through the party members (need press up or down, which switches the modes).

The /assist function would help direct members to a single target based off of the person in charge of the selecting (Dynamis it was main tank)
