I think it’s fairly straight-forward.
Every expansion has zones, quests, dungeons, and raids.
That’s the bread & butter of WoW and on this, each and every expansion can be compared to each other in terms of quantity of stuff and quality of production.
Then every expansion has new features. Those are different from expansion to expansion, but they’re still comparable despite being different.
Delves are different from Torghast, which is different from Island Expeditions, which is different from Scenarios, but it’s all comparable as a single expansion feature of similar production quality.
And every expansion has updates and improvements to existing content and systems. For PvP it’s Battleground Blitz this time. Last time it was Solo Shuffle.
So I don’t really feel this is as confusing and complex a matter as you make it out to be.
I think it’s pretty easy to rank the expansions in terms of volume of stuff, and also easily feel that as you play through them. Some are just bigger game experiences than others. The War Within is a fairly small expansion I would say.
Sure. A new expansion always adds to its previous total, so Retail as a whole will always grow bigger with time.
But I don’t think the lack of size in the latest expansion is excused because Retail is bigger than prior to the expansion being released. I mean, that goes without saying.
I think what’s more relevant is whether I get a comparable amount of stuff for my money in this expansion as I got in previous expansions. And my feeling is that I don’t. I get less. Demonstrably so.
No, I just used it as another example to get my point across. I used other examples previously. I can use others still. It matters not.
There’s no reason why Blizzard can’t make more than 8 dungeons that are also good dungeons. It’s not like Blizzard can only make 8 good dungeons and any more than that are going to be crap.
There’s no excuse for them not making 10 great dungeons, except that players have generally become satisfied with 8 somewhat-decent ones.
Who’s loss is that? Blizzard’s or ours?
