Don't forget Spirit Taker and Mystic Boon. Both of those will benefit from the TP bonus as well, if they got adjusted as drastically as a lot of other weaponskills have. I could easily see the Moonshade adding another 200-300 damage to those. Even Myrkr, which hasn't been modified, gains 5% of your max MP pool from the TP Moonshade; that's ~100 MP for a smn.
Haven't tested the revised club and staff weaponskills yet, though.
