as for ROE, I came back abit late for it, but from what ive heard its supposed to be one of the best(read: most skill intensive) draft environments ever.
as for scars pre-release, building sealed was actually really hard. you really need to cut alot of cards you normally would want to play especially colored ones. i opened an above average pool with sunblast angel, nim deathmantle, myr battlesphere, kemba kha regent and like 2 arrests, 2 shatters and 1 galvanic blast. went lik 3-3. got wrecked by wurmcoil engine and volition reins second round. then by elspeth and contagion engine/clasp/3glint hawks. then final round was close until he dropped a quicksilver gargantuan copying an unblockable... too bad i didnt pull anything worth anything. there were like multiple koth/espeth/mox pulls all over the place.
my fav card from the new set has got to be the "fixed" skullclamp. i LOVE drawing cards >_<
