Things I think need fixing up or changed.

Archers can attack mobs from behind them and on the move but I cant even hit a moving target? And I'm not talking about full board running across the screen I mean, just slight changes in their position on the map.

B. If a monster moves too far to the right or left. Archers can shoot their bow forward and hit monsters from behind, but mages don't have enough common sense to just slightly turn a little bit when a monster is 1 degree outside their casting cone.

Archers cannot shoot behind them, they still have to be facing the target to initiate the attack. The thing you're missing is that all archer abilities are instant, so they resolve pretty much once you use them, like Scathe would for a BLM. The problem you describe with casting is actually pretty normal for games like this and people who don't rotate as they cast to lead/hit a moving target.

Just figured out if I go into first person mode and move my camera it'll move my whole character in place.

I think the thing to pull from them is that moving your camera is different from rotating your character. They seem like the same thing, but aren't.
