Then again, what fun is there going into a fight to get rekt because you just got the wrong skillset?
I for one must say I don't really see it.
Since there are random encounters, the only way you should play not to actually savescum is keep a kind of fixed skillset to ensure maximum security in case of a fight, so basically, several elemental spells, and pretty generic buffs/debuffs.

I don't really see the improvement in terms of fun in fact. I could get it in terms of balance, but definitely fun can not be an argument for this system.
