Thoughts on raid bosses as semi casual player

edit: to make it clearer, topic is more about "world bosses" not smaller raid bosses

Hi everyone, was just wondering if there was a discussion in one of the interviews etc. about the open world raid boss design.

I really enjoy the open system and sometimes it's frustrating as not top notch player to be bitched out by others but in the end this pretty much feels right because you get a lot of involvement in socially within the game

Now comes my little "but": I am wondering if I as a dad and full-time worker (yeah I know my own fault and maybe wrong game for me :P ) will always get the chance to play firebrand and other raid bosses? My group actually hitting max level and crafting a lot so we are well behind the top players and with that spawn times and the ability of big guilds to shut us of the bosses we maybe would never be able to enjoy this content

So I was wondering if there would be a chance to change raid bosses more into instances with lockout times after kills? What do you guys think?
