We might have what you are looking for on the Shadowlands.....Elite
We do have a hardcore raid team but its def. not required....actually our GM is not a major fan of it either but will run when we need him!! He mostly runs the 16 man Sm stuff on any given day with 1 of his alts (His puter is currently down though)!!
Pretty casual, helpful and a good mix of young and old(er) who like to have fun playing the game....We do a lot of our business and scheduling on a website which I run http://eliterep.enjin.com/home and have a imp side guild for alts (currently not very populated)
There is always someone on and peak times we get 20-25!! So maybe check it out
