Hi, i think it would be a good idea to let people spend their pc points on xp in the Pest Control shop, maybe with a daily cap on the xp allowed to be bought (or a very low amount in comparison to regular training) since it is currently unavailable and once everything else is unlocked, there is nothing to spend points on.
The XP wouldnt have to be OP, just enough to make it worth doing to get 200M stats faster. (maybe lock it so it only lets you access it after max stats since before 99 the xp is fast af anyway)
Maybe add some other useful items as well such as Seed / Herb boxes like in OSRS, small amounts of runes etc. (with a daily cap for ironmen)
I dont think this would take away from individually skilling, but would be a nice addition to constantly grinding
Just a vague suggestion to improve the minigame
