Forum:Section headers

Several patch pages for undocumented changed like Patch 6.0.2 (undocumented changes) and Patch 4.0.1 (undocumented changes) use section header capitalizations for regular things like (==World environment==) according to MoS (lower case for non-proper names), but many other pages of this topic use upper case for the second word as well. Now, undocumented changes for Legion and BfA have been changed from lower case to upper case. Which one should be used? --Mordecay (talk) 20:24, 14 January 2019 (UTC)
 * Probably lower case, as per the Manual of Style. -- MyMindWontQuiet 20:49, 14 January 2019 (UTC)
