There’s a difference between recreating TBC line of code by line of code, patch cycle by patch cycle, and recreating the players’ experience playing through TBC expansion for the first time.
I know there’s a lot of opinions for how TBC Classic should be rolled out, but I wanted to gauge a feel for how players (who want to play TBC Classic) want it to be implemented.
Vanilla Classic was pretty faithful to recreating the content cycles, scripting, and game code, but not so much the players’ experience because the content was recreated 15 years after the original launch.
Some private servers have attempted to keep players’ experience intact with some gameplay restrictions that didn’t exist in past versions of the game like stricter anti botting/multiboxing technologies/enforcement and a “fresh” server wipe. We also know now that the there are clear benefits for players to roll Horde over Alliance that weren’t common knowledge when TBC first launched. So some private servers have measures to maintain some faction balance like free respecs for the Alliance only and forcing players to commit to one faction for that server.
