So I left with FULL heroic raiding gear with my DK back in Wrath. I never played or leveled past that xpac. However this coming week I'm building an ew gaming rig and looking to return to WoW. So I ask you what are the major changes? I plan to stick it out with Frost (2H!) and dump my heroic 1H's that I currently have. Any advice is welcome! I do have a few epic 2H's that I plan to use while leveling and what not.
