Oh, I'm just guessing it'd be reverse since people seem to want skill checks to do impossible things without fail, in other words what spells do, with no resource cost. Plus should be easily available for every class with no real investment, since apparently a single level dip in rogue is over the top. At that point, most utility spells are going to be 100% pointless, with only a couple exceptions at best. Then give the martial's other benefits and remove the few strengths of spells, like the ability to target multiple saves. Well not remove it, just make it pointless since regardless of save you will never succeed more than half the time no matter what you target, as his weakness isn't actually weak. At that point, spells are there to teleport and raise dead, and that's about it.
