Yeah the highest I got in any skill was like 75 fletching because I needed rune arrows and the skill balance/alignment really breaks down between archery and fletching in those later tiers.

By the time I got to 70 and had five more levels to go, it was a slog. Once I got to 75 I was like "never again, I'm not doing this for every skill, and I'm not aiming for level 80 in anything either." The reward kinda diminishes at that point on ftp too, like "do I really need to make yew incense sticks? Pretty sure willow sells for more..." There's just no reason to go past 60-75 in most skills

Probably the only other skill I got to 70+ was mining, because I did so much of it while leveling smithing, and the balance/alignment breaks down between those skills too. Mining stardust also helped.
