I haven't read up on all magic items 5th ed... only really started a 5th ed campaign earlier this year...
But all the spells like bulls str/bears end... all gone as far as the players hand book... seems like they got rid of most, if not all the stat boosting/ability stacking etc... does that make a +10 item better or worse here?...
If the above is true and even a full casting wizard cant in any way get his int above 20(i thought at least ioun stones might still boost stats, might be wrong... definitely less options to do so though) i can see even some deciding to take that -1 DC to their spells for 20+ additional build points to make their castermuch more well rounded...
...and if WotC put it in there, shame on them imho... i doubt it though.
...and thx on the ogre-magi... always thought they looked genie-ish... never encountered one though.
