That's just not the case. Myself and many others have had 2200+ arena teams through various expansions. Composition matters a lot and picking a team that has no way to avoid being CC'd outside of a 2 minute potion cooldown isn't ideal. I guess it depends how focused you are on PvP though. If you're mainly interested in PvE but just want to be able to kill people trying to gank you while you're running to dungeons then warrior/shaman will be fine.

Elemental shamans will definitely be a strong pick for PvP once you get a bit of gear. I'm just not a huge fan of shaman DPS in PvE and that puts me off playing them.
