Man, two insufferable extremists of certain ideas arguing.
How boring.
Anyway, don't overanalyze the stupid whelpling. The only thing ever worth analyzing are store mounts, and while there was the Steamscale Incinerator, it was obviously there to tie in with the Mechagnomes, because it came out shortly after or before 8.3, if I remember correctly. Blizzcon/Anniversary stuff never had a deeper meaning.
