Really wish Boris would add some practical uses to some of these skills.
Mining/Smithing
Problem: Why bother, shops sell up to rune.
Solution: Remove rune gear from shops. Require smithing level to join shield halves, draconic visage, and other high level items
Fishing/Cooking
Problem: No problem with food eco, but burn chances are way too high.
Solution: Lower burn chances and add items like Cooking Gauntlets (maybe as a reward for Cook's Assistant?)
Woodcutting/Firemaking/Fletching
Problem: All three skills are completely useless.
Solution: Add as quest requirements, or increase sell price of logs to make this a purely money-making skill. Magic logs for 320gp is ridiculous. Remove Magic shortbow and Rune arrows from shop.
Farming/Herblore
Problem: No problem with skill itself, but seems lazy
Solution: Add 3rd ingredient requirement for potions, and add more of each ingredient to various monster drops. Add Fruit Tree Patches in various locations with actual wait times (between like 10-30 minutes or something depending on tree lvl).
Agility
Problem: Completely useless.
Solution: Add shortcuts and their requirements such as fremmy/brim caves, or certain wilderness bosses. Add run Energy that drains slower and restores faster based on Agility level
Thieving
Problem: Slow to start, and no fun at all
Solution: Add pick-pocketing with low chance of good rewards and chance to fail.
Crafting
Problem: Not too sure, haven't used this skill yet but it seems kinda useless.
Solution: Add things like Amulet of Fury crafting, and requirements for DFS, Godswords, etc.
Hunter
Problem: Where to even begin?
Solution: Complete overhaul of the skill.
Runecrafting
Problem: All runes are in shops, crafting is slow.
Solution: Increase rune multipliers and remove some high level runes from shop.
