Yeah. They did some later corrections (in Spells & Magic, Tome of Magic and Faiths & Avatars) that DR got mostly right... we discussed some of them here. DR missed a few but I never found out if that was by design or by omission (either is fine with me but it helps to know when I'm basing mods or kits off the design).
The 1st 2e PHB sucked, how can anyone think animal summoning and gate belong in the same sphere?
In many ways, DR is a 2e rules mod, so I'm looking at placing your spells in the spheres where relevant. Obviously, you don't want to add a bunch of spells to a sphere that would make some kits overpowered and leave others weak, but that probably won't be an issue for druids.
