So im following guides on what items to get for pve as fury warrior but how do i know what items to get for pvp as arms in this phase? Is there a similar bis list to go after?

Go to raids. Get a purple 2 hander. Go to PvP and win.

there is a section in here that mentions "examples" of good pvp gear

Stack Stamina, Strength and Crit. As always, a solid weapon is your priority above all else.

https://www.wowhead.com/item=12784/arcanite-reaper is pre-raid BiS, and it's craftable. Technically https://classic.wowhead.com/item=12592/ ... of-shahram is better but good fucking luck with that.

Pick up https://classic.wowhead.com/item=13965/ ... ds-breadth and https://classic.wowhead.com/item=11815/hand-of-justice from UBRS and BRD, respectively. Also, https://classic.wowhead.com/item=18834/ ... -the-horde.

And for the love of god, get yourself a https://classic.wowhead.com/item=6041/s ... apon-chain or https://classic.wowhead.com/item=12639/ ... -gauntlets. Nothing will make you feel more impotent in PvP than being disarmed, and once people know you can be disarmed, you will never see or hear the end of it.
