I heard GOG still has BG1 and 2. There you gooo.
But seriously:
1 -> The low level cap(4 on EA), in a campaign which starts with a spelljammer mindflayer ship fighting an draconic army makes no sense.
You deliver zero arguments for this. Why would it not make sense? Because every campaign needs to be a farmboy killing boars for 5 sessions before they can have fun?
2 -> Only enemies seems to be able to summon worgs. Why no PC can cast Summon Monster???
You realize this is still EA, yes? You do know the levelcap is 4, as you stated above. Do you know that Conjure Animals is a 3rd lvl spell? Now think about why its not there for PCs yet.
3 -> On the begining, Larian talked about a short rest after each battle which would make WLK ludicrous OP. Now is a single short rest per long rest which is too limited. Why not something like 3 short rests per long rest? It would put the spell usage of WLK more in line with other arcane casters.
This being EA is probably testing the limits for short rests right now. My best guess is that in a later build we will progressively get more SRs
To be fair, fighting your way through a battle between mind flayers and devils in the Hells doesn't seem to be something a lvl 1 would survive. If we had a tutorial putting us at lvl 3 before getting snatched up it would feel a lot more authentic. Your companions would make more sense too, as they seem too accomplished for lvl1. They are a stretch for lvl 3 too, but it's at least a bit more believable when everyone has their archetype.
It seems suspiciously convenient that you only encounter weak little imps to fight when the devils are responding to a Nautiloid and an oncursion of Red Dragons to their realm. The Nautilloid should be swarming with powerful devils.
Edit: On phone, so grammar be hard.
I don't think it is a big problem that we're lvl 1, but i do agree that it seems a tad too low for us to realistically survive a trip likethis to the Hells. Again, suspiciously convenient enemies that undermines the threat Hell represents, to an extent.
