Greetings, sorry if my grammar is not the best, not my native language, but gonna try to type as well as i can. Just some QL suggestions in my opinion -
1) Enchanting bolts - right now its painful to do 10 at time, make it similar to fletching 100 at time.
2) Slayer Helm - make it possible to imbued, and so it would work as slayer gem, and would free inv space to access log and teleport to task.
3) Buying - buying 50 is great, but if you need to buy runes or feathers for sklilng, maybe you can make instant but possible, so you would not have to make extra click on mouse. (for example holding SHIFT allows you to buy 50 instantly?)
4) Slayer point rewards - the only reward worth unlocking, is to make slayer helm. Boss tasks not working, wayverns avalable without unlocks, same with wyverns, amounts you get etc. Otherwise the points are usless
5) Smithing - the only way someone trains it, is stacking addy bars from shop and making items, 95% are not smelting bars on theyr own. (myself got 4k of ea ore ) make it faster to smelt them or easyer to stack coals?
6) Skilling outfits - to get full Lumberjack it took 15m Woodcuting xp, to get full Anglers im at 150m xp and im 2 items short, without D harpoon.. Is it possible to even it out?
7) Item Stats - furry is better then torture in overall, prayer and defence stats make it huge difference versus overpowered NPC`s
8. NPC`s - overpowered, pvm with maxed gear, and still geting hited so high and often, even when your praying, you get hited way too often.
9) Pets - Decrease skilling pet drop rates
Cant remember any other suggestions
