I agree with the "Pro's" that SP pots are a lazy way to win a quest.
But as with any game, be it PnP or DDO or BG2 or DA:O you work with the resources at your disposal. SP Pots are a resource that are in the game and free for everybody to use. A side-effect of this is lazy players, who blow through their mana in the first part of eDA and use pots to catch up their mana, before we ultimately fail anyways. The ones who conserve their mana and play smart, on the other hand, and have a good bit of no-pot mana when the glorious shrine appears after the third part, those are the players I want to run with.
SP Pots =|= an easy button, they are a lazy button. If the quest is easy enough that tossing back SP Pots will get you through it, then I don't blame the SP Pot users, I blame the quest for being too easy.*
