With F2P coming back, the game (and the wilderness) will (should) thrive again, at least for 6 months or so. Any cunning 'LPCs' will stay 1 defence, keep as low combat as possible and take advantage of the F2P 1-20 wilderness like clans used to. Sure, if you're an 'LPC' and make the decision to go and wait in single for 30 second fights that get crashed against clans with maxed 20 defence accounts, you're gonna have a bad time.
The most fun I've ever had on RuneScape was just pking on weekdays with Calamity and Control, mostly in F2P with 20-30 people (and sometimes, other established pure clans would gather up 20-30 people and we'd get a classic clan fight too). Pure clanning has been broken for many years, you don't need to be infamous or gain respect from other clans to stay alive. Focus too much on how people on this forum view your clan and you miss the point.
