How to do Shadowmourne at current levels? (Unholy/Blood/Frost part)

Is it possible to do this? I have the main axe and have been stuck here for years at this point.

Ive tried doing the plague part before and maybe I was doing something wrong, but just seems like it wasnt really soloable without killing the dude. Anyone have any tips? Wowhead makes it sound easy. Suck up green goos and use them on brown goos. But if I recall my last attempts, it was a bit more troublesome than that.

Blood, I know this requires 3-4 friends to get bit. And then frost it sounds like ‘take 4 ice blasts’. kill boss. Easy enough as long as the damage isnt % based and just a flat amount per tick.

Then back to farming the raid for a few weeks for shards.

But anyone have any tips on this? This is actually the only Lego this character does not have that is still obtainable. Well, except the bows from Sunwell and Sylvanas. But even my hunter doesnt have the Sylvanas bow and hasnt tried farming that yet.

I have a buddy who has the entire thing down to a science. He can do it for you for like 100k. Most people will charge alot more so its up to you. If you like lemme know il toss you a discord link
