I think that the reliance on beast sub-type of minions is a weakness for the hunter because most of the beasts are weaker minions than their non-beast counterpart.
- They are relatively inferior to similar mana cost minions
Ex: Bloodfen Raptor as vanilla card is inferior to other 3/2, 2 mana with abilities
The beast I consider good intrinsically are Emperor Cobra, King Krush, Savannah Highmane, Stampeding Kodo and the 3 beasts created by the spells Animal Companion (which are terrific).
- They use card that rely on other beasts to be potent. This has the effect of weakening the deck to creates successful conditions for those cards.
Ex: Hound Master, Timber Wolf, Scavenging Hyena, Starving Buzzard and Thundra Rhino for minions.
Bestial Wrath, Unleash The Hounds (which is a fairly weak card outside of being part of a one-turn kill combo hence its low mana cost) and Kill Command for spells.
The great effect those cards have is downplayed by the fact that you need lesser version of minions to be effective. While it may looks like striking balance on the surface, I think it is bad for the hunter class.
I think that one of the most important principles in deck building is that every card most be worthy of its spot on the deck on its own virtues AND must works well with other cards in the deck.
That's just not the case for the hunter.
No person in it's right mind will put a Bloodfen Raptor in its deck instead of a Knife Juggler!
It's actually the kind of choice the hunter is facing on every pick.
I have been successful in arena with the hunter the day I told myself to draft good card instead of drafting beast card. I try to apply the same thing in constructed, but I can't because of the relatively weaker state of the beasts minion and the high dependency on beast the hunter has to be effective.
I am guessing that the designer are purposely designing beast minions to be weaker fearing that would make the hunter too powerful.
If that's the case, I think it is a really bad things to do.
As a solution, I would suggest to make beast minions better even if it means to weaken some hunter effect that are beast specific so that beast would be really solid choice in any deck.
Maybe lower the number of cards that depends on beasts to be effective.
What do you think folks?
