Must have warrior items to have later on?

Definitely replace that offhand with a Frostbringer. What's your haste? Getting higher haste should probably be biggest priority in the short/medium term.

Beyond that it probably depends how much you care about soloing.

Embalmers knife honestly is kind of annoying since you have to resummon the bandages every time you log in, but it's still worth having just in case.

Root net are still life savers even if you can't recharge them. Just save them for life and death situations.

Truncheon of Doom + Silken Whip of Ensaring + 2x Blood Points is my go to for soloing on the warrior.

With a good damage bow. Not much you can't take out as long as you can get a snare off.

Being able to run full speed at low health is basically warriors most underrated skill.
