jagex Logics

tbh the main reason for the whole effigy thing was just to remove any possible incentive that would cause people to camp monsters for effigies to avoid training the actual skills in the way that they are meant to. I don't think Jagex has a *huge* problem with people hoarding xp that can be gained quickly, because if you think about it, there are all sorts of ways you can do that: Dungeoneering tokens, flash powder factory points, brimhaven agility tokens, vinesweeper, squirk juice, collecting huge stacks of summoning charms, etc..
