I think now is the best time to actually think about this, because with the level squishy and the change in leveling overall, the whole old worlds content has to be reworked anyway, so basically there is no better time to adress this than now.
Raids have always been a core aspect of WoW, as the game went on, more and more work went into the raids, and most of them ended up really good.
Seriously, playing WoD Raids is my most positive memory of the whole expansion, and I am not even one of the big WoD haters… the Raids were just that good.
So its kind of a shame that they just… well, rot away now. Sure, sometimes Transmog farmers or gold farmers visit a few older raids, but wouldnt it be much better if you could actually do them while leveling?
With the Shadow Zones (dont remember the real name) in the next patch, we actually get content that scales based on how many people you take with you, so why not rework the old dungeons and raids so that while leveling, you can actually do them with 1-5 people and actually get a good experience out of them? It wouldnt even be much to change, I think the mechanics that a single player cant do can do are in a very managable number, and for everything else it would literally be enough to push some numbers around. Every Old raid that can be done solo by a max level player would work just fine with only number changes.
And from the top of my head I can only really recall 2 raids that I couldnt finish alone, and thats the Insect one in Pandaria, because that one boss traps you and another player has to free you, and the other one is Hellfire Citadel in WoD, because Gorefiend bugs out and resets when you are alone… And Hellfire assault is a nightmare for every class that isnt super mobile…
So, what do you think? With the new “level as you like” concept Blizzard is aiming for in Shadowlands, shoudl the raids be reworked to become part of the leveling process?
