I'm a new player and have been levelling WHM as I enjoy playing healers in MMO's but I am considering moving to AST for 2 reasons:

1. I think they are the best looking class I have seen so far with some great looking spells.
2. I see WHM is in a bit of a slump at the moment.

I was thinking of continuing WHM to 60 then buy the level boost for AST as I don't want to go back and have to relevel.

My question and point of the post is if I take this option I'm concerned that it will be difficult transitioning with all the new abilities (as opposed to learning them slowly through levelling). I am generally fairly competent in healing MMO's but very new to FF so don't have a huge familiarity yet.

Do people think it's reasonable to change over like this or will I struggle with the new class at that level?
