That is pretty much the reason that I expected to hear. :O

I might forge mindlessly ahead to try it anyway. Can always rebuy Curtana via the Salvager and start over, right? -.-;;
There was this moment back when I was levelling Arcanist (still haven't gotten it to 50 yet) and I was doing a low-level dungeon with a fully-leveled and geared out Scholar, and his (same) spells went by SO MUCH faster than mine. I think probably the effect is greater than estimated.
