I wrote PvE scripted environment, smartass. Your two examples (chess and SC2) are PvP, not PvE. If you think the RNG and AI of Ragnaros HC is anything near as complex as the AI of a chess computer which sports insane amounts of CPU power then I rest my case. The quick reflexes required in SC2 are unmatched in raiding, the very top end of WoW raiding gets near that level. Add to that the very top end, while not coming near there, is the exception to our discussion which is about median of 25m raid, not only the top end.
