Blizzard has seemingly been slowly but surely making a deliberate move towards giving magical damage for all classes, which is really starting to skew the survivability capabilities of certain classes about wow gold. For example, at level 70, although paladin (and obviously druid as well) survivability was incredibly high partially because damage was a lot lower, it was also high because the viable melee/ranged classes (warrior/rogue/hunter) had no spell damage attacks. It was pure physical damage and as a paladin I was sporting something like 60% damage mitigation because of my plate armor about wow gold.

However, there has been a disgusting trend for Blizzard to introduce things into the game that weaken the strength of armor. The release of WOTLK introduced the death knight, which is all magical damage to get World of Warcraft Gold. Hell, even using hand of protection on somebody that is dying to a DK will do absolutely nothing to keep them alive to get World of Warcraft Gold.

In WOTLK hunters got explosive shot, a fire damage attack on a 6 second cooldown in the survivability tree. As many people know, hunter damage along with the TnT stun was a constant target by protesters on the pvp/hunter forums.

Of course we cannot forget about retribution paladins, who although have been a terrible specc through all of 60 and 70, have been very successful and obscene in arena at level 80. And, as many people can assume where I am going with all of this, they also have a lot of magical damage, which cannot be mitigated.

Finally, we cannot exclude rogues from this list. Even though rogues do a lot of physical damage, they also have that pesky wound poison, which does about 500 non-mitigatable damage every time it is applied on the target. And do not kid yourself if you think that is not a lot of a rogues damage, because it is.
