Pretty big difference between "without explanation" and "I don't like the explanation." For one, the second one isn't demeaning to the people giving the explanation.I just don't find any of those meaningful or significant.
They’re just different spells. They’re spells, but from a different source and maybe a lil weird, but not really that special. Near as I can tell. I am sure I’m missing something because every time Dark Sun comes up there’s a grip ton of hand wringing about getting Psionics right. It just seems like spells to me. Spells with a different but not much different rule system. Sorcerer, but with unique spells. I don’t get why it’s a big deal and why it’s not just a different spell list. Help me understand. Or confirm, it’s just spells With a new name.
IMHO, that is what a lot of the argument boils down to at the end of the day: i.e., the thematics.I think I just like the thematics more than say I like arcane magic.
