I don't know about everything else, but I do know that this situation is perfectly suited to Alaira. I propose 'Shock and Awe' as our strategy here. We scout around the camp, with the process like so.

First, Alaira identifies the mightiest or most important targets, and initiates the battle. With her batteries, she has a guaranteed kill on anything they have if she gets the first blow. We have her attack first in the flashiest, most explosive way possible. This will cause chaos among the bandits as they try to gifure out just what the fuck is happening. 

The second that happens, the others join the battle, taking advantage of the confusion to more easily dispatch the surviving bandits. Then, the bandits are forced to decide which of the threats to engage. The crazy half elf in the middle, or all the others who are all attacking from different (preferably) directions. Alaira is a formidable warrior, she can survive as long as backup is dividing their attention. This also means that everyone that isn't Alaira is at less of a risk since they aren't in the middle of it all. This might appeal to the group's subconscious, as they aren't too fond of her right now.
