If u join bg with the trinket, you keep the 44% cd reduction, so cloack of shadow and shadowblades, and vanish at 44% less cd. But if u use the pve trink inside bg, the 44% its reduced alot.
Should be reduced alot even if u join bg with the pve trink, like inside arenas (in arenas is fixed).
cross realm
7/10 cuz its for bg, not for arena
