Wowhead doesn't have a changelog for the transcript, but the old transcript on wowpedia said 4.[1] And the official site did say 4 in an early version.[2] Here's a more recent version of the website stating there were 5.[3] --Aquamonkeyeg (talk) 16:19, 2 June 2015 (UTC)
- Just guestimating from the archive links, it looks like 4 was at launch, then 5 for TBC, then omitted in WotLK. --Aquamonkeyeg (talk) 05:08, 3 June 2015 (UTC)
