Is this something the Old School RuneScape Development Team are looking into implementing to Old School RuneScape? I've heard about it from somewhere and it sounds like a brilliant idea.
It's spoke about but it's not confirmed by osrs yet I believe. No official posts on it anyway. It's a feature which is coming to RS3 and will probably follow osrs shortly after.
It seems fun and cool to think about. But how active would this game mode even be? You group up, player for a couple of weeks and then your partner gets bored and leaves you. Now you're stuck playing normal ironman.
Also, I'm not sure on the idea of "sharing xp". So you're allowed a group of 4 and all 4 have 50M woodcutting xp. That would put them at rank 1 for 200m forever? Hmm, seems odd. If this was to become a thing, I wouldn't mind the highscores main page be sorted by the groups total. so if the rank 1 team was 2 people both 2000 total, then the "Total Level" for that group would be 4000.
Although, honestly. Don't think it would be all that active on Alora.
No support, too much work for Omicron for too little players who will actively stick too it.
Edit: Ofc though, if there was high support for this then it'd be fun to see get added. I wouldn't mind seeing it with enough support.
