Mr. Warg provided in the Beta forums a nice list of warg changes. Hopefully he'll be able to itemize them here again. The sum of it is a long list of cooldowns for many of our skills. Some make sense, some don't entirely. No armor boosts or any long-fight survivability increase, except for the new corruptions every creep class gets. However, I wouldn't cry too hard. With Loremaster stun immunity going back to sane again, the warg's CC should be viable again. Yes, that's right! Entire freep raids won't be immune to our pounces anymore!
General PvMP Changes:
They added more corruption slots, with bonuses if you are traited 3 of the same, or a bigger bonus of 6 of the same. The bonuses weren't that impressive to me. Some issues were noticed with diminishing returns applying to these bonuses. Perhaps another player can elaborate on this better. I didn't spend much time on it, unfortunately. Believe it or not, I spent more time on my freep toons testing out class changes.
Hunter Class Changes:
I'm sad to report that hunters are going to hurt. The good news is that their DPS is OP, though I'm sure it will be nerfed again in the coming months. (We always are, eh? But this perceived OPness may be coming from overly easy landscape mobs.) The bad news is that it takes fewer brain cells to kill things. Agile rejoinder is gone. The hunter cry skill for putting a fear on animals is also gone. Rain of thorns is buried in the Trapper of Foes tree, tier 3 I believe. Rain of arrows is similarly buried (tier 3 or 4) in Bowmaster. Running Bowmaster, you can get Rain of Thorns back easily enough at level cap. However, getting both at levels 47-50ish (the original intended level range) isn't going to happen, due to the double-point penalty of investing in an alternate tree. I feel bad for hunters in mid-range levels. It's going to be a very dull adventure without those skills. Heightened senses is restricted to ToF as a passive. You absolutely MUST trait ToF as your specialization if you want heightened senses. This is going to be bad news for PvPers. Finally, crafted traps/lures/snares are being removed. The devs say they'll make crafted augments for our built-in trap skills. In the meantime, your stacks of traps can be converted into ingots by a weaponsmith. I, for one, will miss my crafted traps. I'm sure many weaponsmiths will be counting the days until they can craft the trap augments.
We did get a few wins. The devs initially removed our bubble, but after we testers begged them, they brought it back. The devs had likewise removed Bard's arrow, but have returned it as a base skill everyone gets rather than a tree skill. The same happened with swift bow. ToF also didn't have inductionless traps as it does on live, but the devs fixed that as well. They also made range targeting of traps optional. I found it rather annoying and clunky, so that was very nice of them to let us decide how we want to lay down our traps.
Despite these small victories, the hunter has been dumbed down further. Getting back all of your old skills won't be possible. Many of them are emergency "panic" buttons for when we get in over our heads. I'm very sad to see them gone. They're like old friends. We are now a one-trick pony. I have personally tried to adjust to these changes, but I think it's safe to say I don't think I'll continue playing my hunter any longer. It just isn't fun anymore. Let's face it: Getting in over our heads was half the fun of playing a hunter. All of that is mostly gone.
I will, however, leave you with a few more positives. Huntsman is interesting. You can fire on the run! ToF has been given some perks as well. It feels a lot spiffier damage-wise. All lines have new skills. Some you might like, some not. They're mostly "blow things up" skills, with relatively little brain power involved. However, don't take my word for it. It's best to try it out for yourself, and decide if you like these changes or not. I personally am not a fan, but that doesn't mean the changes won't grow on you. But I will warn you that I have chatted with other hunters, both on the forums and in Beta, and the general consensus seems to be that we all feel dumbed down. So be prepared for a shock.
Loremaster Class Changes:
The Ent legendary skill is now buried neck deep in MoNF. However, the Eagle is only on tier 2 of KoA, which is somewhat encouraging news. However, accessing it at level 45-50ish (its original intended level range) will be costly if not traited for KoA. KoA is the strongest the three trees. The others were meh. AN needs more love. And that's not just my opinion. That's the general consensus. A lot of skills are missing. Your skill bar will look like swiss cheese. To get the most skills back, you can go AN, but AN seems to lack a punch. It's meant for group support more than anything. However, I am not a full-time Loremaster to give you more details. I fiddle with an alt from time to time, but mostly play with my hunter. I leave it to the more experienced Loremasters to fill you in.
