So, I was on the parkour server, and then I went to the Lily Pad parkour in Easy. Yet one of the first jumps is 4 blocks. (For those who don't know, a 1 block jump is easier than sitting down, a 2 block jump is as easy as sitting down if you're sprinting, a 3 block jump is slightly difficult, and a 4 block jump is OH GOD SO HARD.) The same thing is also in Cactus 1 except with a 3 and 1 up jump (which is a little bit easier than the 4 block jump but still hard). I'm sure I've run into these on other Easy parkours, but I think 2 examples is enough.
