Legend
D&D spells have been written with stat blocks for many editions. It's useful for lookup and settling rules arguments. If spells are going to have technical facts (ranges, damage, casting time), then they need to have stat blocks.
Call of Cthulhu, in most editions, has spells without stat blocks. Many spells in that system have vague effects, or things that are open to Keeper interpretation. Great--magic should be like that in CoC, but not in D&D.
Mixing in all the stats with the text makes the rules of a spell less clear. It's not something I'm interested in.
No one is suggesting getting rid of stat blocks. i find them useful in the first three editions. People are just asking for the spell description to once again blend mechanic and prose (while retaining a stat block entry).
