For F2P: There wasn't really a combat triangle, you could use magic while wearing rune armour, and it didn't effect your spells, same goes for ranged. Next, all weapons had the same speed, so everyone used a rune two hander. The skill of PKing consited of "catching". Catching ment you sort of went a bit faster then your opponent and "caught" him, this was done by a combination of timing and clicking in the right spot, mixed together with your connection speed. Seeing RSC had the 3 round system, meaning, you couldn't run for 3 rounds, the ability to hit often and high was very important. Also, it ment you could only eat after those 3 rounds were over, so if you were able to hit 3x20, and then catch your opponent, he wouldn't of been able to fully heal.
