Blizzard has tried hard to make so much of the game smooth and fun, cutting out factors other MMOs think necessary (like, say, corpse runs or XP loss on death) because they recognised they’re not fun.
Take tradeskills. For the most part, they’re streamlined and simple to execute – I have some issues with the amount of reward they offer, but there’s no “because we can” obstacles…
…except in Enchanting.
If I’m levelling up Alchemy on an alt, I can give her a couple of stacks of herbs, a stack of vials, and click one button. I walk away to get a coffee, I come back, I’ve got a stack of elixirs in my bag and 20 shiny new skill points.
Getting those skill points for an Enchanter? You have to execute your recipe individually each time – and if you’re grinding your skill up a bit, you’re probably re-enchanting the same item over and over with the most efficient recipe you’ve got. Each re-enchant requires an extra click to confirm that you really did mean to overwrite the last enchantment on the item, which is identical anyway. So your twenty skill points cost you forty mouse clicks instead of one, and a lot of boring staring at the screen. It’s as bad as fishing, and you don’t even get to get out and look at the scenery.
It’s only a minor niggle, and the world’s not gonna end if they don’t fix it – but it’s so jarring and tedious in an otherwise streamlined world.
