Pest Control is always dead? I've done PC at the quietest times of the game and completed games fine. No support whatsoever. People would also get upset if they lost it and had to pay for the untradeables back.
There's been talks about this on every runescape platform. IMO this is a better idea then Classic mode and should have been brought out instead. Classic modes eco is already ruined from revs and is mainly used to make money for normal mode.
1 slayer point per pick up is a bit expensive. I get the point of the item but eventually there would only be like 2 people using it. Plus, are telling me you get a 72 air Rune drop and that'd steal 72 points?
I think using 100-500 points to make it during your full slayer task would be better.
