I wont mind it in FFXIV, when someone is gear swapping and you have target on him you pretty much re-target the person when they blink. Unlike FFXI it was a pain in the butt for healers without using a 3 party tool but i don't think they ever allow us to gear swap.

Gear swapping could help out a lot get better nuke gear or best WS gear but let's see if any of the dev team would replay to this topic,.
