Question about class

[Niwashi]

If you want to do both, couldn't you just put your skill points into intellect only? Then for the summoner side your set. For the scholar side if you have cleric stance as your additional trait, then you can use that to flipflop your intelligence and mind stats. Or at least that is what I do with my scholar/summoner.

You can put all the points in either and do reasonably ok, but one job will be slightly weaker. With all points in INT, it's Scholar that will be weaker. Cleric Stance can't fix that for two reasons:

One is that switching the INT and MND stats is only one of the three effects that Cleric Stance has. The other two are that it improves your attacks and (pretty drastically) weakens your healing. So you never want to be healing from Cleric Stance.

The other problem with this approach only comes up near endgame, as you start getting job specific gear. Regardless of the bonus points that you can put wherever you want, a lot more of your stats will be coming from gear, and healer gear focuses on MND.
