Awaclus claimed two things, that Nomad Camp is a bad choice in the opening and that during the game he'd prefer Woodcutter. That boils down to claiming that Nomad Camp is worse than Woodcutter which implies that it'd have to cost $2 which implies that DXV made a big blunder while designing Nomad Camp.
Obviously this is wrong and I don't know why I am even responding to him or you.
I've made lots of mistakes, so I wouldn't end with "...implies that DXV made a big blunder" as if that got you anywhere. You have to figure out how good a card is separate from that.
A key thing to understand here is that costs in the $2-$4 range are very similar. The differences for most cards boil down to 1) openings, 2) +Buys, and 3) perception. Here you don't want to load up on either, so +Buys isn't a factor (even though the card itself means we know they're available), and the Nomad Camp opening is deceptive, it does give you a shot at a Woodcutter/$5 opening but it passes it off as a $4/$5 opening, which it isn't. What really matters though is perception. Nomad Camp looks like Woodcutter with a bonus, and so has to cost more than $3... because there are some people who hate strictly better cards! I got to use the term the way I like to. There are people who hate it if one card is strictly better than another, and there's no pull the other way, no reason I need to make strictly better cards. So, Nomad Camp costs $4.
I said "most cards" because sometimes the cost is relevant to the power level in some sneaky way; the example I always think of first is, Border Village was too weak, so I raised its cost from $5 to $6.
Anyway Nomad Camp is of course intended to be Woodcutter with a bonus. Most players do not regularly draw their deck, even if they'd like to. Sometimes you are lamenting not having +Buy, and Nomad Camp gets it into your next hand. But when you're drawing your deck and decide oops now you need +Buy, putting Nomad Camp on top hurts your chance of drawing your deck next turn, since it's a "stop card." And some players draw their deck often enough that therefore overall Nomad Camp looks worse than Woodcutter to them.
Nomad Camp is of course worse than lots of $2's and $3's, including some that give +1 Buy. It's impossible to avoid, especially when e.g. you can't make cards strictly better than Woodcutter.
