The shadow form increases the priest's WOW WOTLK Classic Gold armor and damage from shadows but blocks him from casting spells that fall within Holy Line, including healing or the resurrection spell. Additionally, the disciplines line of talent revolves around increasing resistance to things like stuns the silence of spells, interruptions in addition to enhancing stat-boosting spells as well as mana regeneration.

The mage class has been streamlined by allowing spells to do less damage than previously the ability has been removed and casting time has been rearranged. The class seems a bit weak at the moment, and it is a reason why there aren't many players playing mages.

The cap on levels was raised to 55. Additionally, some new high-level zones are now accessible thanks to the patch -- like Felwood as well as the Burning Steppes as well as The Ungoro Crater. Additionally, existing zones have new music, like Darkshire along with the mage's quarter of Stormwind. Mini-dungeons of a smaller size were added to several existing zones, too. A new system of sharing quests was introduced that allows characters who have an unspecified quest to "share" it with their group, as if have given the mission. 

The system of quest-share cannot be used to avoid tasks that require an element that is required in the form of previous quests in the chain, or the search for a specific object, however it lets parties participate in the identical quest without having to divide up or travel back to a city in the first place.

Traveling has also been upgraded by the addition of new flight lines that connect all regions and the addition of boats and zeppelins in the games. Zeppelins and boats can be used to connect two continents: Azeroth in addition to Kalimdor. They are always in motion which means that it's an issue of waiting at the drop-off location until the boat appears after which you board. 

The cross-continent trip currently doesn't take much time at all (there's currently a "warp" in the middle with a superimposed map screen), and the craft are accessible to both Horde and Alliance characters, making trips on the faction-versus-faction server risky business.

World of Warcraft also continues to improve slowly in different ways. New spell graphics are being added to specific spell lines. Additionally, new models were added to the panther and tiger mounts, which are used by cheap WOTLK Gold 
 the night race of elves which made them bigger and creating a more intimidating appearance.
