For those quoting Bigby, Tensor, Tasha, etc Remember those were names removed from the game. Perhaps that speaks to their viability. Although, I would argue they were removed because they were from Greyhawk and the original authors campaign figures. They were descriptive despite the name.
Why not call is Spell shape, Spell sculpt, Area adaptation, Spell bender.....I can go on and on for names that have a more description.
Why do I want description...two reasons:
1. When I am 30th level, I want to look over my list of 15 talents/feats and know what it does when I haven't used it in a while.
2. When I play in my underwater sea campaign where there is no such thing as a wyvern, I'll know that the feat makes sense in my setting.
