[Suggestion] Spectate for raiding
So I know what you may be asking as to why should this be put in the game and the simple answer is to help your friends who are stuck on a certain part in a certain fight this way you can go and spectate the fight and see each players buffs/debuffs/positioning/cooldowns and see where they're going wrong, this mode should also add a spectate chat or put the chat into something like alliance that way its separate from party chat and can easily be seen.
I know some of you may be thinking why not have it so that someone streams the fight and my answer to that is; they may not have good internet and they're camera might not be in a good position to see where everybody is may be or may die.
tl;dr add a spectate feature for raids to help friends get further in a fight by giving advice and telling them what they are doing wrong.
