I'd race you any day.

If you are allowed to build a ton of fires to get your Screamers coming, then I am allowed to pre-plant 1000 trees in a tight forest.
You can build a dozen fires day 1 knowing almost nothing about the game, and all you need to survive minihordes easily is some open ground with a few obstacles, an iron club, maybe a half stack of arrows?, all also easy day 1 material. Maybe some barbed wire to string them out more, goose your kill rate. Fifteen minutes' fuel for a dozen fires, okay, getting that done by day 1 too with enough daylight left to not be fighting at night that early, not so easy, call it day 2. A newbie paying attention and lucking into the right sequence could discover it pretty early, I noticed I got screamers if I tried to light the outer walls and defenses with torches, that was the first time I ever saw one, it was day 2 or three I think.
Steel tools you get by day 7 only with substantial luck or experience, and to be reasonably sure of steel tools with the steel to maintain them, by day 7? I'm not close to that good, maybe we're really talking about different things. Iron tools and a forge day 7 I can be pretty sure of. 'cept the hoe, those are, like, nowhere to be found, I had to google for it and google told me garage storage, I think I went trhough every damn garage in diersville. No hoe. Hoes are the gift of RNGesus alone it would seem. To be fair, I don't own a hoe, my friends and family don't own a hoe, I don't think I know anybody with one, so maybe we can call that the "social commentary" part of the gtame.
I don't have a problem with disparate leveling rates. You being level 53 as a miner doesn't make your guy better than my level 42 looter, think of classes like genders and levels like shoe sizes or something. The question is, are we thriving? Yes? Screw the numbers. No? Screw the numbers. If this is competitive, competitors don't compare apples and oranges. My apple's better than your orange just doesn't have a whole lot of zing.
