Least involved class/job for struggleing player

[Enkidoh]

Welcome to Eorzea!

If your wife is having trouble with class mechanics, a simpler class to learn on might be Archer (ARC) as with that you just have to simply target the enemy and shoot arrows - the only real complex aspect of it is when you are on your own you will have to keep backing away from the enemy to avoid attacks, as ARC doesn't have much defense, meaning they can't take much damage.

Don't feel down about how your wife is doing though - you've both just started and you'll both pick up these things with time as you go along (I've been playing since version 1.0 and I'm still learning!). The early dungeons especially are meant to be pretty easy to help guide the player into the mechanics of party play, so you do have some leeway in making mistakes. The important thing is though, have fun!
