D&D General Is it right for The Pcs to choose to not go up to 6th level straight away simply because they'll be too strong for several very good adventures?

Reason 2 is that 1 of The Characters is A Druid and The GM was foolish enough to let The Female Druid, that has A Male Player, go for size and power over variety and numbers, even worse is that its 1e ADAD, this means The Female Druid has 10HD of Animal Friend and as far as I know this is the only edition were A 5th level Druid has 10HD rather then 5HD worth and The GM was even more foolish when he decide to let his Male Players Female Druid get 1 5HD Owlbear and 1 5HD Giant Crocodile

Yeah, non-animals is a problem. But why do you keep bringing up the genders of the character and player? That's got no impact on the question.
