I am playing a Lizardman Druid, and while I might play a lizardman again, I doubt I will play a druid again based on my experiences and the comments I have heard from another druid player.
The class is cool, but it seems that some GM's and players don't know exactly what to make of the animal companions. Some GMs seem sort of parionid that these critters could give too much of an edge, or don't want to deal with another NPC to keep track of. And some players keep thinking their companions are attack dogs, literaly.
My own GM was pretty strict about my animal companions. He also continualy forgot to keep track about my animals in combat, until gave that responsiblity to me. In additon to that, he contualy found excuses to have them run off from unnatural enemies (we kept running into undead and demons from day one in his games)
Now that I am 15th level and my spells outstrip any dire lion I could have, he seems pretty happy, though he keeps acting like I am whining if I we have to leave my animal behind (as when we teleport across a continent).
Between that and having only Entangle when we do dungeon crawls all day, I am opting for a Sorcerer class/multi class next time.
