What is so bad about War/Rngr
Furrycat
Using beast spec so your pet causes max damage...as a war you are basically just running around meleeing etc.. and the pet acts as added damage. In PvP it's even better since no one goes after the pet (I assume) so it is like an endless DoT.

There is nothing bad about warrior/ranger. I am one I should know. I have great attack, have a pet, and can heal a little. What more can you want. Great combo if you ask me.

Its not bad per say but its just that a warrior primary has low energy and a ranger without expertise has very costly skills if you find a set of skills that isnt affected by this then *shrug* more power to you.
