You can also use a spear main hand and a tome off-hand, the game chooses the tome as the casting tool. Tomes are still viable, they just block someone from being an omnigod kung-fu curate master with a two-handed polearm.

I also think the main reason for this to not be moved to Curate was about said in details by Spo. All in hope that Curate has yet some (more broken and absurd) things to gain in the future that might promote synergy between their own or other class. Like Demon Hunter and Spellthief did. (Maybe even Boxer to an extent)

Also, Magic Moon being like that also opens the possibility to balance out, trading STR for WIL while keeping the amount of points spent relatively the same, so you can also get more FP and Elemental ATK on all stats, without losing much on STR if it's being an impairment. It's what I often do to detour having to spend points in STR, with a STR/WIL weapon.
