Honestly i see where your coming from i really do but Raids are End game activities and are supposed to be Very difficult & challenging mechanics wise, look at the raid from Destiny 1 Wrath of the machine. I Absolutely Loved that raid but i liked how difficult it was and that everyone needed to be on the same page & on the ball or else it team would wipe, but if you want to raid make your own raid group. But if you put up an lfg post make sure you state that you've never done that raid but your willing to learn it will take time to get the mechanics down yes as not everybody learns mechanics as fast as other, but as long as your honest in the lfg post saying you've never done the said raid but are willing to learn you'll probably be able to get a pretty understanding team to help ya.
