User blog:Tenebraeh/Free Unit of Choice Question

So, basically, since we're going to be able to choose any unit from Gildorf Batch and backwards, I'm not sure of what to get...

I have a lot of great units, but I am missing some units, like Charla, or Avani, so I'm not sure whether to get one of those two, and if so which one, or just another unit in general?

Anyway, tell me what you guys are getting, and if you have any suggestions, go ahead.
