Going in blind into the Gith fight can be dangerous. I'm sure a lot of people will struggle with it the first time. But then again, a good portion of players will probably encounter them at level 5, which makes the encounter much easier. They get two attacks? Well, so will your fighters. And your casters will have access to level 3 spells which are quite potent.

I did manage to survive the encounter the first time and I didn't know what to expect. Gale dropped fast but I had two fighters (my character and Lae'zel) so they managed to soak/block a good amount of damage and SH helped with heals. I didn't know about food at the time so I drank a ton of potions but in the end I survived with my character and SH still standing. I'm sure I could have taken them at level 5 fairly easy without prior knowledge.
