It appears like the combat thing is making the game seem more like WoW..? That's not a negative thing Imo. My ideal scenario is a dungeon-based system as WoW with RS Gold healers tank, dps, and healer. That's a lot of. The EoC as it is sufficient to take RS out of its dead combat mechanics. You've certainly never been PvP'd...
To be honest, EoC IMO isn't good or bad, however I'm guessing it'll eliminate bots, which is a plus. Anyway, Dungeoneering isn't something you can really explain, there were some clan wars-related updates for F2P However, overall F2P hasn't seen much..
I've played with PvP on the Beta. It's pretty great. PvP is a thing in Live however, is another matter. I'm not rich enough to be able to replace all of my lost equipment, so I generally don't go up north. Also, I don't have the over-loading herblore.
However, I personally would not classify PvP in the current combat system "dead combat" though it's an issue of opinion. I'm sure that fighting many non-boss monsters using the current system is pretty boring, but it's going to always be that way.
EoC won't make fighting non-boss monsters fun... It's just going to make you spam your abilities. I've played with the Live game and Buy OSRS Accounts it's wonderful. In beta, I'm PvP'ing... In the moment, it's awesome. Everyone gets Full Torva/Pernix/chaotics whatever.
