This isn't really a "new" issue, but I would like it if you'd extend the beach of the first area a bit. You've got some open space there, anyway, and it would really make grinding for low levels and pearls less annoying, since new players wouldn't spend as much time doing nothing as they wait for crabs to respawn. If you extended that beach a bit, even if you only managed to add in one more crab pack, it would make it seem a lot less boring at that level. I also would like to see the level 5 lobster back; I remember in the very early version, there used to be, before the bridge, two level 3 crabs and a level 5 lobster. They are now just 3 crabs. It'd be neat if that level 5 lobster was put back into that spot with them. Just for the variety, and also because players wouldn't want to only fight level 3 crabs at that point anyway, when they'd gotten that far.
There are way too many level 1-2 wolves, all over the place. Level 1-2 is a pretty short level range, and they give basically no experience to players who've reached level 4. It would be nice to see the wolves that are in the spider area be higher levels, maybe level 2/3 rather than 1/2. Not important, but it would really make the game more enjoyable for lower level players.
It would be nice if there were some level 7-10 creeps... There's just a huge level gap where players don't have anything good to farm besides d1 creeps which are overpowered when you have only one or two players. It would be nice to see you add just one group of enemies somewhere in the first area that are level 7/8. Maybe, rather than a random drop chance for the sealed scroll quest, have a level 8 bandit mini-boss on the beach. Not as strong as a normal boss would be at level 8; rather, give him something like 900 health, with a couple of level 7 bandits at his side. Since he'd be weaker than most bosses, his gear drop would obviously not be as good for his level compared to other bosses, but he'd make the game more interesting.
The cloud in the water is way too bright. Looks like snow. You should make the cloud thinner, and more transparent.
The first two suggestions aren't anything new, but the last one is specifically for this version.
I like the weather, day time filtering, and new terrain, but sometimes it seems like the lightning flashes are red, black, and pink... Should be white or very light blue.
The mercenaries seem pretty well balanced and I like them, but the shaman one is a bit triggerhappy on his heals, wasting all of his mana when we have 90% of our health.
I haven't gotten far enough to try the talents yet but I'm really looking forward to it.
