This is so so wrong. You are meant to learn through trial and error. This is supposed to be the hardest PvE content in the game, do you really think they should hold your hand or make the mechanics similar to everything else in the game? Mechanics are precisely what they should change and make more difficult than all the other content rather than just mobs in greater numbers or making them all massive damage sponges. Both of the latter are tedious and uninspired, mechanics are where it's at. You're supposed to sloppily fight tooth and nail to struggle and limp through this end game content for the first time and then be rewarded and feel satisfaction when you do repeat runs far more efficiently and effortlessly. It's a mark of progression, improved teamwork, and perseverance. I can tell you my whole Raid team is hyped as hell to go into Crota's End completely blind and battle to learn how it works. We'll get our asses kicked learning and then we'll come back to kick Crota's ass when we have it all down. That is satisfying. If you are just reading everything online, you're doing yourself a disservice and are missing out on half the fun but fun is subjective so maybe it's just not your bag.
