Buy WotLK Gundrak Run and complete a dungeon by killing all the bosses, gaining various high-level gear and preparing your character for the next raid.
The dungeons in WotLK Classic are much harder than the retail WoW dungeons. Bosses are harder, mobs are stronger and there is no quick LFG system. You have to waste time looking for a team on your own. However, with our WotLK Gundrak Boost, all these problems can be easily overcome.
