With the way fatigue works in the playtest I'd go for option 1, tbh. Getting fatigued mid-combat made me pass my turn several times instead of attacking and hoping those -1-4 AC wouldn't screw over my already-sluggish Titan Mauler.
Also, I didn't realize until mid-session when playing my barbarian, but the rage bonus to damage stacks with pretty much nothing. WHY?! Pretty much every time someone else from the team cast buffing spells on us I'd just go "meh, yet another damage increase that won't matter to me"...
