So im going nuts here. Recently got back into wow, quit around 2008.
Im playing retail and main is 80 ret paladin.
Been chasing some transmogs etc alongside m+.
Now im aiming to get the default/base ashbringer.
Looked on wowhead, said i need to go to Eastern Plaguelands and get a quest from Lord Maxwell. Got there, getting a different quest… 
got tolded i should go to Warboard and do the Legion thingy there. Did that - got nothing.
Someone told me about Chromie and Legion campaign but as i am lvl 80 i cant do that.
Can someone please point me to where i need to go to get the base version of Ashbringer?
