This way You can wear barrows armour which is one of the best ( Not that expensive either ). People still wear rune in P2P, and it's not a sin to wear it :) GET 70 - 70-70 and get Torags With Whip, Rune defender, d boots, glory ( purchase a Mage Arena cape to start off ) and a Combat bracelet. the rin goof wealth.
