I started playing around July 2022, up until December and afterwards took a 5 month break until now. I currently have 16 characters which I like to play. I currently have a 6/6/4 rest rotation for chaos dungeons and i completely skip guardian raids and only doing LOPANG for dailies not leapstone. If chaos/guardian was changed to 1/day of each while keeping rest bonus, I would be able to do guardian raids as well. Legion raids take up most of my time in a day as i usually can play 2-3 hours max per day due to school, gym and wanting to keep a regular sleep schedule. I don’t think legion raids are particularly too hard, but I think they take up a lot of time. For me, the most enjoyable parts of the game are guardian raids, legion raids, abyss raids and abyss dungeons, but playing them on new characters and gearing them up to be stronger is much more fun to me. I am required to “sacrifice” a character each week to be able to earn materials on it, regardless of gold. A majority of my alts past 6 are 1445 but because of my time constraints I am usually unable to get them their relic pieces. Roster/Character bound mats from a modified version of a legion raid could serve as a way to learn legion raids as well as help players who want to gear and improve alts with little time.
TLDR: 1 Chaos/Guardian Raid per day while still keeping rest bonus. Add a seperate option to legion raids which would be slower, easier, and shorter to teach legion raids which only grants roster/character bound mats.
