I mean the server consists of mainly Irons and PvM, so you wouldn't destroy the integrity of the game even if you put in an RS3 style PvP toggle because theres no real PvP. The closest thing you get to real PvP is during PvP events, or 1v1ing at edge ditch. Otherwise it's just hunting rev caves, skill spots, and tele-to-target runs on PvMers. I'm not trying to take shots but i'm just calling it as it is. Look at all the people who go on 100+ killstreaks, they login like once a week to ego boost off a broadcast and don't even fight anyone who fights back or risks. I get your frustration as a PKer you want the game to work as intended, but it already doesn't since the skill of hunting targets is no longer in the game as long as you can teleport to them. I have no problems with any of your other suggestions, I just don't think we should make it even easier for a PKer to kill a target after they tele when you already have the biggest advantage of being able to teleport directly to that target. If you don't believe me just go and look at the Server Media section of the forums for PvP content, shits been dead since Peeks, LADS, Liths, etc all stopped. When we had clan action the wild was fun, there was tons of funny banter and content, now it's just ego boosting.
You keep referring to "ego boosting", maybe the toxic single clan members who still login from time to time but you can't brand the whole PvP community with that. There is a reason why all the PvP has left the server, it's due to lack of bug fixes & reason for the wilderness to be populated not to mention lack of marketing towards that side of the game. I cannot stress enough how much potential this game has to revitalise the wilderness & that scene. With the launch of the mobile app coming soon, this will hopefully bring an influx of new players, these simple implementations will aid in keeping normal players who enjoy PvP & the wilderness.
