Must have warrior items to have later on?

[Tunabros]

Some few items I can think off top of my head are ring 10 and wracked cord and maybe a regal band down the line?

Any other suggestions?

I am currently playing on green and my warrior is leveling very steadily. Warrior Epic

shouldn't be too hard at the moment and my guild should cover it for me <3

Atm I am using a WESS and a lamentation. Is the infestation or frostbringer better procs?

Should I stick to just slash (only)?

Thanks!
