Not exactly. The majority has been Lvl 150 for a while and has been playing this game almost from the very beginning of The West, so they don't need tips on how to play, although we do have many players who are not even Lvl 100 but I think it's because nobody has felt the need to rush anything. Comradery as in how willingly you see many jump to help when other players require assistance, be it crafting or questing or whatever. As I mentioned, Col. Mortimer sells his extras at cost after the tombolas, no strings attached, in the open market for whoever needs the item to complete a set. He could list three guns of the same kind, and we know he wants three different players to grab one each, not one player to grab all 3 and upgrade. We can have a season quest that requires some shop gear (black shirt, green shirt, etc.) and a player will remind the others to check their shops and list a bunch for those who need it. Players can ask for a high level recipe and a lot of players would sell them at cost, regardless of friends or alliance ties (alliance there is more a nominal thing, it's not like there is any rivalry at all).
The leveling XP thing was indeed team work, not because those 30 something players (dubbed The very best of The West by some) needed any hints to know how to do it, but the couple of high levels who started that crazy experiment would hand them products to advance with the questlines, give them the shop gear they needed as they leveled up, etc. Nobody told them how to skill or play, or the class they had to choose. This was World 8, the year the tombolas started, before they added new quests almost every month, and before you could use the bank to transfer money. The fanciest thing we had at the time was the Golden Gun. It was not an Inno sponsored thing, just a bunch of friends having fun together. The player who leveled up in a week did have a lot of help from many of us who enabled it (give her gear and products, rank her captain as a low level with a precise rifle, etc.), but she didn't need help to know how to do it. We actually helped that adventure because a) we were her friends; b) we were curious to see if she could pull it; c) we had fun watching it unfold; and d) lots of the old timers saw her as a test subject and learned many, many things that they'd later do themselves. She taught us, not the other way around, and a couple of times some of her theories ended up with Inno nerfing stuff to correct flaws they didn't know about before they could be exploited (a naked greenhorn throwing rocks and finishing the top damager of a big battle, due to stacking). I can only give you the general tips about her leveling method, as the game has changed since and new quests have been added that would rocket it up if tried today.
