Ferocious roar is bugged when using socketed warcry skill

It seems that ferocious roar uses both skill but you only benefit from the socketed one

The description says that it only uses the socked one

But mana usage and endurance charges are used by both skill the main and socketed one

Not only that but mana cost is bugged also.

Like when you don't have a socketed warcry my ferocious roar costs 46 mana and when casted it used exactly 46 but when i socket infernal cry even with a tireless gem it should up the cost by around 40 mana but when cast with infernal cry it uses around 120mana.

So mana cost is also bugged.

EDIT:Nevermind i just checked the ferocious roar skill and says it also adds 200% cost multiplier for the socketed warcry.
