@M.L. Martin Do you still have the text of the DL anti-canon? I remember really liking it but I do not have it saved anywhere. I used to be on the old DL Forums under the name of "Tinker".
Such spells fell under the domain of Mysticism, and since there were no characters classes you could have a character with up to three schools of sorcery and three spheres of mysticism. And even wear armor and use weapons if you have the stats for it.:)
I hope they do not retcon anything after Legends. I loved the Fifth Age and the post War of Souls world. Far more gameable material there than the War of the Lance era.
Sorcerers have been in DL since the Dragonlance SAGA game technically, although it is not the same as the 5E Sorcerer. The 3.5 supplements had to use the default 3.5 Sorcerer with some tweaks to the flavor (DL Sorcerers are not Bloodline based, but learn their magic like Wizards). I have no idea...
I honestly would have preferred more base classes over Prestige Classes, but I like a lot of classes.
EDIT: OH, one thing I would change is the required magic items to hit certain monsters. I would change it so say a Devil requires cold iron weapons to hit, not a +3 sword or whatever. Or all...
I started on 3.0 and then moved to 3.5 once it came out. Looking back on it my group ignored A LOT of rules. There were also some "rules" that crept in from video games and such. Overall 3.X still feels the most like D&D to me, especially the artstyle. I still have the basics of the ruleset...
I would let a player play an elf or halfling etc. of whatever color they want. I do not see the big deal as we are playing to have fun in the first place so my players having fun means I have fun. Same thing goes for LGBT characters.
