There isnt anything powerful here in PvE maybe on pvp have his uses because of knockback but compared to every other 90lv CD dps talent is meh
For me it's Death Siphon. Awful damage, crappy healing and all for the low price of a death rune.
Beast Lore. Does any high-level Hunter use this ability even once in their (WoW-)lifetime? Last time I've used it was back in WoW Vanilla as a low-level Hunter whom didn't know how to play and therefor just pressed buttons randomly.
Although I see Earthquake is a strong contender for "most undertuned". It is just sad that an ability that is meant to be a spec's signature AoE, a DPS spec at that, does such low damage. I always thought Blizzard was great at designing classes but sucked at tuning them properly afterwards.
Exorcism. Once you have the haste to push it out of your rotation you will barely ever use it (Maybe once a minute in that one time that both CS and Judgement are on CD) and you waste procs because there's no point to use it.

Next time you guys log in, Blizzard should freeze your character, spawn your favourite mount and shoot it in the head. - Mormolyce
Bloodthirst, Flamestrike, PW:B, Arcane Torrent, Jab, etc. are not anywhere near relevant levels of uselessness here.
I'm not a native English speaker, and yet, I don't suck at English. The argument "English is not my mother tongue" doesn't actually give you an excuse to do so.
On-topic - Blood Strike (completely useless), Feed Pet (why is it still in the game?), Flamestrike (can't it at least be useful to cast in more than 1 situation?), Earthquake (why would the most overpowered AoE class need such a useless spell?), Hurricane
