They wont remove the meta otherwise casters and rogues will go nuts cause a mount reward will be the only reason people go back there and people will still need to farm those instances for cinders etc
I do agree that the drop rate should be lower on guaranteed mounts but i dont think it should be 1 percent cause its not like anyone will be able to solo or even 5man heroic raggy anytime soon i mean they should let people have a realistic chance of obtaining them maybe a 10 percent chance would be better
Even as a full group as level 90s that fight is still unforgiving to inexperienced players
