This only applies to keyboard/mouse users. I think we have an advantage over controller users. Thanks to Cliff's hardware mouse patch I can finally say that using the mouse is the absolute best way to target enemies and allies. Why? Since the lag is gone, the mouse is very accurate at pinpointing a single target with a click of the button. It is faster than cycling through targets to the one u want. It is so accurate I can be far from a mob, click on it and it will target the mob.
One of my biggest concern was the target/tabbing system in XIV and the fact that the cursor was too laggy to be useful for targeting. I am actually enjoying the game now more than I did before. I used to be really grumpy about targeting because it was a pain when u have 3 monsters beating on u and ur too busy tabbing to one of them.
Other thoughts- I recall someone here said AOE spells only affect enemies in ur leve. This is not true. I experimented by fighting my leve mob and running them near a galago. I turned on AOE and faced in front of the leve monster and galago. After using the spell, it hit my leve monster and the galago. I hate it when people spread false facts.
