Double fortitude gain: Getting two points per level is ridiculous and since effects the amount of torpor you get when hit by a torpor attack such as a scorpion or titanboas you want it to be fairly high so you don't get knock out by one while you are off your dino for whatever reason.

Increase Crafting Speed to 50% per level: This may seem like a pointless skill but it is very useful when it comes to making custom recipes as how effective they are depends on your crafting speed: http://ark.gamepedia.com/Custom_Consumable use the table about half way down on the right side to see what I mean.

Increasing food and water by 30-50 points per level each: In my opinion the 10 points you get when increasing these stats doesn't make it worth while to put any points in them at all, so increasing them by 30-50 points will make it worth putting points in them.

Stamina: I suppose an argument could be made that increasing the stamina gain by 30-50 as well would beneficial as the 10 points is to low but personally I haven't ran in to stamina problems in a while and all my characters have the base amount of stamina of 100 and I do just fine.
