What I think may happen is that you gotta commit to the tadpole companions? Maybe you gotta choose who is gonna get saved and then maybe we'll meet more companions that don't have tadpoles? Like we save Shadowheart and might meet some people under shar or selune. Who knows. I like the companions so far but we are lacking in what Dos2 had with interesting side characters that stick around (The halfdemon-elf, the necromancer, the kid who looks for stuff,) Then again this is only the first act and we don't know who is actually gonna stick around with us. Who knows.
