Pretty sure it's not a viable weapon anymore

if you're not going to push through higher gr, then this weapon is still pretty viable from tier 30 and down.
heck, this is still useful in T6! and the drop rate on this weapon is or i think was buffed.. so it should be available through rift and certain grift levels.
i still have mine ancient and non ancients as throphies.
