WoW: Burning Crusade Classic differs from WOW Classic in that it focuses more on the way various raid bosses hit real-time servers. In the original TBC days, the developers seem to have made significant adjustments to all opponents that existed in dungeons or WOW TBC Gold raids. In the original World of Warcraft, on the other hand, subsequent simplifications were made only occasionally, usually through bug fixes or the removal of time limits.
When the developers announced TBC Classic, the first promise was to show players the original Outland, not the nerfed bosses. However, there still seem to be some exceptions. In the new version of TBC, Magtheridon's health is significantly lower than before.
Earlier, Blizzard had also announced that they wanted to implement more decay at some point in the classic version, just like they did in the original TBC. At first, it was said that Blizzard wanted to make nerfs work when the next phase went live and guilds stopped focusing on content, and this has been nerfed.
Kael'thas, Vashj and Co. in TBC were significantly nerfed before Phase 3 began. However, future stages of PTR testing often consist of a rough mix of pre- and post-Nerf content, leaving you never sure how the battle will ultimately play out in the live version. Also, the nerfs to the Phase 2 bosses were already in place long before Phase 3 Buy WOW TBC Classic Gold started.
