In terms of the talents are concerned, like all the other talents you'll have to choose what will best suit your needs depending on your personal gaming experience. We noticed that items that enhanced the spells WoTLK Gold mentioned above were the most beneficial and therefore things such as Improved Moonfire, Improved Thorns, Moonglow, and Moonfury were on our list of items to look for, however there's no shortage of other talents that are related to spells within the tree. A good option for almost all players would be Omen of Clarity It can be cast again when it wears out, and can allow you to cast spells with no mana cost, and all for the affordable cost of just only one point of talent.
Feral Combat The Feral Combat spell tree is somewhat more clear from a distance as compared to other spell trees because they're a simple ability that, in the majority of cases and work with the Cat and Bear forms. There are plenty of capabilities here, however they'll require costly level-ups if frequently use your other forms frequently. If you're able to afford it however, you'll need to master all these abilities, since they'll make the shapeshifting form more useful.
These Feral Combat talents, though they are the ones where you're likely be forced to make difficult choices, particularly when you're switching between shapeshifting forms for combat, and humanoid forms for healing in groups. However, the majority of abilities are applicable only to one type of shapeshifting or the opposite in a limited way, with only a few abilities (such like Sharpened Claws) affecting both. This could allow you to specialize in one particular form or in the event that you are having a greater use for one than the other. However, the same thing happens if in the event that you divide the points of your talent in a more or less equal way it will only give you the advantages of half at the same time. Because they are so important, it's an issue of waiting until you've gotten an idea of the manner in which you're likely to be using in the class prior to buy WOW WoTLK Classic Gold distributing the points.
