I like Tiny Tina, but I think her character needs to develop. The reason why I can laugh about her craziness is that I know she will be ok. She has friends and can care for herself. In Tiny Tina’s Assault on Dragon Keep the others show that they care for her and Krieg also hopes to become sane. It would be the logical consequence that she become more sane.
Who will take care of her?
Brik: he is Tina’s BF, but if the Vault hunters though about it, like people do when they make important decisions, they will probably come to the conclusion that it’s a bad idea. Lilith: She is not really good with people. Springs and Athena: Springs writes violent children books and Athena is quite patient with her. No one, like before: This war_is_coming_stuff, is a good reason, why someone should take care of her.
Will she become a playable character in BL3?
The events of BL2 happen 5 years after BL1, if BL3 happens 5 years after BL2 she will be 18. I think her character already needs to develop. And they also managed to turn claptrap into a playable character. So maybe?
I think this is a good base for a discussion. Now give me your opinion and reasons would also be good, a bunch of people that just state their opinions is not really a discussion
