Pits shall be more useful here than in your normal average world. First, players can't restart in BP so expect potentially less barbs. Other than that unit speed modifier is low compared to many other worlds. This decreases farming efficiency compared to pits (although still farming is still way better, pits are now slightly more useful than usual)
Another thing is if you have just a few farms, you may find axes useful. If you don't have enough farms, you may have to make them yourself: with axes. Although it will most likely put you behind compared to a player who got lucky with his area and is pumping out LC, but it shall work better than just focusing on LC while not having enough farms. Sure you can still risk and wait for other players to clear each others out but if they don't, you may suffer.
About the new coin price, yes as you all can say nobling has become more efficient. I think a lot of players may try to noble earlier than what they normally would do.
Oh! And the most important part: Don't forget the hiding place!
