Baron, at the risk of derailing this thread, it seems to me like you're not factoring in the Temple's casting cost. It's not two mana for a two-dice attack, it's eleven mana for that attack. And then thirteen mana for two attacks. Only at three attacks does the Temple break even with Pillar of Light, at fifteen mana. Finally, once it's used four times, with seventeen mana invested into it, it's finally starting to come out ahead of Pillar. And that doesn't even take into consideration that Pillar of Light is a rather poor attack spell in the first place, that Pillar of Light still has a better Daze/Stun chance, that the Temple is locked in place and can be attacked, and that it needs to have another temple card in play already to even get that second die of attack.
I stand by my previous statements: the Temple of Light would have been fine if AW had just removed "adding X to the effect die roll" from the original text. As things stand, it is a Hell's Gate card, largely useless now.
