I'm a bit divided about this. Having us choose the setup of the group is convinient. I wanted that too since we can control it from lvl 2.

But immersion wise it is good as is. Even not beeing able to control the lvlups of the other partymembers would be ok for me. So they evolve like their character is written.

And i must say that i never really had problems with her dying more than the rest of the grp when attacked by multiattack x5. Her Half-plate is a good armor and at lvl 4 you can give her dex 14, that would give her an AC of 17. not too bad.

But all in all this is a player preference.

P.S.: This is the least toxic forum i ever wrote in. :O
