Point was settled.
The game group voted (by email), and four out of five of the "off book" feates and options the player of the Druid asked for were rejected, including the Greenbound Summoning feat.
The feat is so imbalanced that even CharOp boards typically note the expectation that DM's won't normally allow it. This is the expected result.
Afterwards he said he didn't want to play with us, that he felt our style and his weren't compatible. I can't say that he's wrong.
I can say that I wish he was.
I played with a group on a long running 1e campaign that went through a RL years long period of 'paragon' tier play as kings leading armies into battle and eventually went through RL years of 'epic' play with interplanar travel and apocalyptic 'alien' invasions. After I left the group, they rebooted a new campaign with a grittier low magic feel as a change of pace. A player asked to join the group. He arrived with a character sheet for a game that at the time was 3rd level, with his loot already filled out including a Vorpal Sword and a Wand of Wonder and about a dozen other potent items. At the time, the group had a single magic item - a +1 dagger. They tried to explain the situation to him, and tried to explain to him that generally speaking, characters can't just choose their own loot (remember, this is 1e era, long before 'wealth by level' and fungible wealth and magic marts are accepted as a thing). He got mad, stormed out, and my friends had a long laugh before shrugging their shoulders.
Do you really wish your style was compatible with the player? Where you voting to allow it?
