Suscribers with field respec can switch between roles quite easily, but it still takes longer, than should. The idea is simple. As suscriber when you make a talent placement, then the game saves it, and whenever you switch to it you get that one back. The reset button would serve to place the talent points again.

 

Also suscribers would get a quick button on the portrait similar to companions to switch specialization, when out of combat.

 

The main reason i would use is for veteran fps. For clearing adds that healer is really needed, but when going on boss, then it's pointless. Just switch to ranged dps, and keep using koltos in most cases. The second reason is quickly switching while leveling, and then back to healer/tank when the fp finally invites.

It's interesting that you didn't mention the other thing that people normally mention about field re-spec: ability layouts on action bars. The selected utilities (in the "K" panel) are almost-but-not-quite irrelevant, since there are only eight.

The depressing thing is on the specs i swap between regularly, I know them so well, swapping specs takes all of 30 seconds, if I'm slow.

 

I'd rather them fix bugs or do something about the disaster of a gearing system they just created.

 

Its obvious they only have the time or talent for one thing at a time.
