Going by the thing of setting there were warrior kings rolling around in this age who could drag a pair of ancient red dragons down to death with them, solo styles, because the elves of this era were just that mighty. But y'know, we top out at 12th level. We're not those dudes. If magic is intended to be the deciding force of everything as regards the campaign here and just blow past everything, circle magic and all, then other than to be in submission to such, why even have non casters or not just do a Netheril campaign.
Ugh, that didn't come off great. Look, I'm not wanting to be Canute commanding the tide here or step on anyone's fun or start a multi poster arguement. If most people are cool with the Hathran thing, with circle magic, what have you, then go with it. I've just in the last few years become a lot more used to pathfinder, where things are generally more balanced out, and the games I've been part of have not really involved people optimizing that hard, such that not quite optimally building to conceptual shtick worked out fine for comparative effectiveness.
I don't know, I'm probably going to do some rethinking on my concept and build regardless.
