Sigil of the Master Assassin

[Udead]

Hello,

Legendary item for rogue Mark of the Master Assassin buff not showing or working in arena. Please check. Works in BGs, duels, PvE.

Going in arena with Mark of the Master Assassin legendary item won't give you the buff for critical.

This is pretty gamebraking for a rogue main, that tried hard to farm this legendary just for arena :(. 

Already reported in bugreport too.  (https://firestorm-servers.com/en/report/see_report/108314)

What are your thoughts on this?

Update: It's not working in BGs either.
