Not receiving experience from great long axe in 2h mode

[brave_chicken]

I also dont receive any drops With Great Long Axe or Long Axe doesnt matter if in Polearm or 2h Mode

If this is the case I assume you're using the great long axe used by warlords/vet zerks. That is because there is no polearm mode for those axes. Only the one you can purchase allows both modes.
