Which creatures from the alternative upgrade options do you choose?

1) in defense, because they are tougher. 2) because they look like homeless people) ragged and live in miserable huts. 3) strangely enough, my grammar is actually quite good; I just sometimes deliberately write incorrectly) to add some variety to my speech. 4) so, what about the Shamans? Am I wrong? Do they have something that I haven't understood?
