stratholme as the worst - because ive been trying to get the charger from there for ages and still hasnt dropped

MgT - as the best because it can still be challengin even with the best group/gear

Are you talking here about the Paladin's Charger mount ?
Because that's in Scholomance, and it's a quest o.O

Just asking. Maybe I'm confused.
Unless it's sarcasm, ofc :-)
