... Hate to break it to people who think every area in Broken Isles scales but they don't. There are areas that are 110 only outside of Suramar. Highmountain has an area like that on the northern coast. If I recall, I ran into one like that in Stormheim as well. Don't recall if I saw one in Val'sharah or Azsuna, but I'm sure they're there, too. Eye of Azshara (the island, not the dungeon) is also 110 only as well as the Broken Shore (post scenario). So not everything scales. You aren't going to be able to go where ever you want at level 100.
The maps feel okay but they also feel really cluttered. It reminds me of the Hallow's Eve and Winter Veil dailies in WoD. They shove 20+ people into an area the size of our garrison for a good many quests. That only makes it frustrating. For the most part, many quests let multiple people click on items, but there's still a good many where clickables aren't shared. I did one world quest yesterday in Azsuna and found myself fighting not only for mobs but also anything to click. And with the area being so tiny, you're running around in circles for 5-10 minutes trying to find SOMETHING to progress your progression bar. Yeah, there's more use of the areas so there's not really much dead space, but shoving 20-50+ players into a sardine can fighting over the same things isn't exactly fun. I'd rather Blizzard had found a better way to even out players so we all don't get bottle-necked in the same areas. Scaling zones honestly doesn't seem to be helping any.
It feels really really small, in fact, a lot of the new zones do, because blizzard started packing stuff so tighly together instead of spreading content out and allowing zones to have some width and breadth.. so it feels smaller than it really is.
it's smaller, there is no doubt about that. However it's pretty dense, Draenor is probably technically bigger, but that's because of it's shape, there is a lot of dead sea area between zones, there really isn't any dead areas in lost isles, so it's smaller but better.
There are still very much 110 areas, you just have to go out of your way to stumble across them. In beta, I, like many others bumbled around without my favorite addons, side quest sent me into the mouth of a mine, which turned out to be a huge mining operation, with multiple layers and the whole place was teeming with kobolds (and the legion). There were a bunch of rope bridges spanning a central chasm, and I decided to be brave and leap over the edge and glide down a few levels to see what was hiding down there.
Well, a world quest group elite ate me. I respawned at the graveyard a few floors up, and ran screaming from 5-6 110 kobolds. There were a few treasures down there as well, sadly I didn't live long enough to get to them. When I finally made it back to my corpse, I hearthed to Dalaran and marked the area for 'later'.
TL;DR- Legion looks small, but feels huge.
People seem to think empty space is bad I like it. It makes the world feel not so cramped. For example the Cracking Plains in Frostfire Ridge are largely just empty space but it really creates the feel for the zone.
Hi Sephurik
It will feel big until the crappy flying is enabled.
I played a lot on the beta and can say it definitely feels larger than Draenor or at least on par. It might even be a little larger than Pandaria when you consider how massive Suramar is. We also have to remember they're going to be adding at least one new zone in a patch.
