Question about vanilla instances

Are vanilla instances all open? Or those level 60 are unavailable?

Thanks.

Certain raids like Naxxramas aren't open.

Hello Ostlimpa, raids ok but instances like Brs, Ubrs, Stratholme, Scholomance and Brd are they open ?

Yes they are.

Oh yeah thanks firend :D

Almost all vanilla raids are bugged:

-MC loot table is 100% bugged
-BWL first boss is bugged
-AQ40 has manys bugs too

They are doables but you have to tryhard or dont expect to loot everything ( Ragnaros didnt droped any loot last time I killed him xD )
