Well,do as you like bro.Im just saying that I did quite a lot of pvp with felguard(yes,felhunter is better) and when my guard runs out of mana,and he DOES quickly,its just worthless.You cant intercept,you cant cleave...
In my opinion,you should put AT LEAST 1 point in mana feed.imp HF isnt a must but i like it more than 400+hp hs.anyway,good luck with your felguard and peeveepeeing
