He says a few more interesting things that may shine some light on Blizzard's questing philosophy, which I'll discuss after the jump.
For example, He also points out that variety in quest types is needed to keep things from getting too boring, and it's a fair point too. Most of us, after finishing up Nesingwary's quests in Stranglethorn or Nagrand, probably feel like we never want to see a quest to kill massive amounts of wildlife again, so we'd likely get to feeling a bit drained if every single quest involved killing massive amounts of the same thing over and over again. He also mentions that if they did remove random drop style quests, they'd probably have to start bumping up the required number of kills for "Kill X amount of mobs" quests, which might suggest various internal metrics at Blizzard that must decide how much a person should have to quest or kill to jump up a level, or how long a quest hub should keep a person in an area.
He ends by stating that he believes the WoW team is getting better at implementing new quests and making new mechanics to build off of for future quests. The game really does seem to hold him out on this, as we've had plenty of new and exciting things do in Outland, from stealing the souls of gronn and going on bombing runs, to jump-starting the hearts of Fel Reavers. If nothing else, the philosophy Drysc expounds bodes well for players as we head into 2.4 and the expansion, since if Blizzard continues to build quests off those ideals, it means we should get some good, quality game play out of them.
Of course, we'll probably still have to kill 30 Shovel Tusks for good old Hemet.
So what's your take? Is variety the spice of life? Or would you rather not waste time waiting for one last Forest Troll Tusk to drop?
