Sadly I have to agree. Vault Hunters can’t really get too much backstory as playable characters, when they appear in the next game as NPC’s we’re pretty much meeting them for the first time.
I liked Maya from my years spent with her, but I really didn’t care too much for her. They didn’t give me a reason to, we just call her in for backup then watch her die a couple missions later. Roland’s death was actually better, somehow, because we actually got to see his relationship with Lilith/brick/tannis/etc and actually feel bad for those characters because they seemed genuinely upset over his death. A stark contrast to “it’s war people die,” briefly muttered by the one character that doesn’t care about anyone.
