They should have just lowered the CR IMO. Compatibility be damned!I'm honestly not sure what the answer is for 5E. Arcane Burst came about for the same reason that monster damage increased so much in the 2025 Monster Manual... because the old versions weren't hitting as hard as their CR would recommend, at least not without customizing their spells and running them super optimally. (And don't get me started on the '14 mage having only 40 HP at CR6).
Arcane Burst is clumsy but it may be necessary idiot-proofing.
