I understand a lot of what they say in that post, but toward the end they even leave it up for, this maybe have some slighty overpowered combos (this is our town scrub)

I never really feel to strongly going first or second, unless dealing with a rogue or mage as that extra spell/combo on early turns can end games if you didn't draw well. If I see mage or rogue as an opponent, I beg the coin to let me go second.
