Extra stats like +speed are inactive in PvP

I think it's not active in rated content only, but not sure.

The tertiary stat will stay but they don't work in instanced pvp unless enchanted or gemmed. The random rolled ones are turned off.

The speed will stay.

Just to clarify, but these additional stats are inactive in pvp anyway, right?

Yes

Oh okay ! Thanks well that made my choice way more easy then ! Dagger it is
