I actually think the Loh world quests are pretty cool in concept, and I enjoyed doing them the first time around (especially after Loh got a speed buff). But after you've guided Loh in all the different locations, of which I only really remember about three (Tiragarde Sound and two in Vol'dun), it's the same puzzle every time. Blizzard needs to have many multiple different Loh puzzles that change every time you do the world quest! Who's with me!?
