What is your suggestion?:
Add the proper minigame/content to receive skilling sets.
Is this in OSRS?:
Yes
Has this suggestion been accepted already?:
Checked and haven't seen similiar suggestion
How would this benefit Alora?:
Putting all the current (or any) skilling set in a single shop with daily tasks seems a bit of an easy way out to fixing a problem. Personally I'd like to play content related to the skilling set like in OSRS to achieve it, just like how we can play MLM to get full prospector.
I don't know if it would make it more, or less, grindy to get the full sets, but I think over-all it would be better to make us closer to OSRS. Some updates may take longer to implement if it's a larger minigame attached, but I think it's worth the effort.
