If they can't match them AND the Empowering is limited, then lugging around baggage like casters who can keep up with melee only two times in a dungeon is pointless.
Haha that sounds like what everybody says about low level wizards in D&D though, except instead of unempowered spells they have sling stones.
I've asked Josh Sawyer about this and gave him a link to this discussion. My suggestion might seem logically bizarre to him, because the idea was "if we make spells cast slower, then we can also make them more powerful". But Empower makes spells even MORE powerful, so how could they be fast? He might reject the idea out of hand because of that. But I hope he considers it.
It seems to me that a big issue with Empowering might be that people are so turned off by the slow casting speed of spells in PoE2 that they don't want to waste
any additional per-rest resource on them. It feels like
"throwing good money after bad". If the spells are so damn slow then at least they're free, right? Fundamentally they don't need the spells to be a bit more powerful, they need them to be faster. Arguably, even an Empower function that
only made spells cast faster without making them more powerful could be worthwhile.
