If you don't think highlander priest - 'in certain games' - as i stated didn't require more thought and planning than most (imo, all) of the T1 wild decks right now then i don't know what to say.
Most are all about creating unanswerable board states early in the game. Burn/Secret mage is about chipping them down/killing them before that matters.
Are you seriously telling me considering your resources, especially with everything a 1-of unlike in big priest, didn't require more thought?
Sure, there are games where the highlander priest didn't have to make meaningful decisions either. But plenty where they did too. Especially because it's not like T4-5-8 highroll draw/mulligan was an everygame occurence.
Sorry to burst your bubble but other than a streak of Dragon Priest during the Blackrock days i've never played all that much priest. During december of last year i actually took a krul renolock deck to legend which had a horrible matchup against highlander priest.
And idk what you call "high legend" since at least on EU, on average during the middle of the month or even later i typically got legend 60-75 when entering legend rank (so not like there are that many legend players in Wild).
But yea, let's just dismiss my opinion because of your preconceived notions.
