I've been testing on dummies for awhile, and it may just be the parser not counting dot's correctly, but I do more dps just doing DK > TS > SP from the flank. If I interchange SP and refresh demolish when its down, I parse at 255 dps. If I only do DK > TS > SP from the flank only, with steel peak, and howling fist used during gcd cooldown, the maximum I've gotten with relic is 268 dps. Until there is a reliable parser to prove otherwise, I'm finding demolish and other dots for MNK worthless.
