Standard caveat, proof-eating all that better idea after the 24th.
I like the design goals. Spikey damage, skill monkey. Not being a hairy footed sexy god of war is not a bad thing.
A rogue can sneak in, let the wizard and fighter open up, and drop the healer. Nice. Burst then fade, if you can't fade... Haaaalllppp! It's a return to 1e, or mimicking video games, whichever you prefer.
As more of the L&L come out, 'the fighter, fights' gets reinforced more and more. A wire fu ninja taking on a mob of guards is a fighter with an appropriate theme and background. A ninja as mystic invisible assassin, sneaking into the stronghold, killing the daimyo and stealing the ancestral family sword, is a rogue. The classes have become better dance partners, less toe stepping.
I am intrigued by the thought of a burst model of damage for the rogue. The hints dropped early on of the wizard and fighter being balanced in damage output asymmetrically, fighter every round, while the wiz casts fireball on the third round, makes me think that the rogue will be able to duck in and out of combat a bit to build up to a big hit every couple of rounds.
Come on 5/24!
