BiS Gear

Ok this is probably a minor thing, but anyone else slightly concerned that a majority of BiS stuff comes from the last two bosses of the raid? My main has like 6 items from those two and my alt is the same. Talked to guildies and they are similar. On top of that only 3 items on my bis list are from M+. This doesn’t seem like the best way to do it. I would have preferred gear be more spaced out among different sources.
