Agreed. It has a lot of 'must have' skills like Farlight, Eternal Flame, the innate RES. So you tend to only have like 2-3 of the main spells maxed out and a smattering of 1 pointers for utility sake. 

I'd probably go a bit further and suggest applying the SP crunch to things like Skyhigh, Raging Flame and Bask in Light.

The other big thing it could really use is Eternal Flame becoming a passive skill all the time, rather than only if Main Class. It currently limits a lot of pairings that also want to be Main Class since Eternal Flame feels necessary for Lantern Bearer to function well.
