I feel as if this game needed more tactical fights in which positional play contributes to the overall success of alliances. Constantly, the types of strategies needed to be employed on many NM's is based on either a "Zerg" based strategy or a PLD tank strategy. In these situations, the outcome is always a static frontline/backline role. I suggest that there would be new types of NM's that demand tactical positioning in order to be successful.

Example:
A NM with a tail that is flat. (Wirve modified) Timed fight, medium sized area.
This NM will employ normal strategies of a PLD tank except one of its TP moves gives a 3-5 second animation queue that would suggest that it would start running away. Once the queue animation ends, it starts running, and it will run at flee speed for 2 minutes, making it difficult for even RNG's to shoot it.

The tail is flat like a platform however, and will have a queue that when people step on it, it "depresses". The strategy needed to defeat this NM is to react when the NM starts to queue the "run". When this occurs, enough people must step on it's tail in order to stop it from running. At this distance, only BLM or RNG will be able to damage the NM while they stand on the tail. Perhaps, the new key item "Lodestone" may be useful as well. But in a full ally battle, at least 6 members of the ally must be on the tail in order to immobilize it.

Example 2: NM with two TP moves with different effects depending on amount of people.

This NM would have two TP moves which will alternate serially.

TP move1: Deals damage based on # of players (Will deal more with less people)
TP move2: Deals damage based on # of players (Will deal more with more people)

In this fashion, the alliance has to coordinate the amount of people in range of the NM during each situation. After TP move1, the alliance will have to evacuate to make sure that TP move 2 will not kill everyone. After TP move 2, everyone has to get in range of the NM to ensure that no one gets KOed.

Conclusion: Fights as I have suggested will add a team coordination aspect making it necessary to communicate and adds a strategic element that the game had lacked.
