Woah woah woah. Don't stay at path to oops that long. It got slow sometime around 5x, I'd say you can go to Path to black Swamp early (55~?) and stay until 60, do the electric snail quest (Easily jumps you to 68) and then train out there a few more levels until you feel confident, that you can take on Swamp Shark/Arachne's.
I did beaver's swamp(Swamp Sharks) until lvl 87 which I currently am. It's still pretty good experience. The alternative is Bugbears/Jokers (Path to snow Hills). It's good because you can get a party, but bugbears are a pain in the ass, and with all of the power/charm types all of the jokers are easily killed, so you have to be very fast, and vigilant.
I had pretty much the same problem, so you can check this for more information
