Raider.io exists because of all the risk of running keys is on the leader. I don't fault players for it at all tbh. I also don't apply to +10s when I've only done +2s even if I have the ilvl for it and will do like a 5 then 8 then 10 to ease into it a bit. If it wasn't IO it would be ilvl or achievements or armory anyway. I hope blizz will change it at some point but they seem to really like doubling down on dumb decisions lately even if current mythic+ is a few steps up from the past.
Ive never seen cactbot but I have heard it compared to WoW's deadly boss mods which means it doesn't do much if that is all it does. FF has huge arrows telling people what to do and they still mess up. Knowing about something doesn't make it free though. If anything I wish this game had real addon support but I do get it would kinda suck for the console players. At least FF has much better base UI control so things like hotbar and bag addons don't feel as needed. I refuse to play wow without at least dominos(hotbar addon) at this point though.
