I think the Gith patrol is supposed to be equivalent to the Duergar squad in the Underdark, both covering exits to Moonrise Towers (and the end of the Act) So making it an easier fight doesn't seem like the way to go. In my experience(I went there pretty directly my first patch 5 replay), It's difficult to reach before level 3, which makes it a hard fight but not impossible
The problem is the duegar one (probably) has favourable terrain for the players, and the enemy health and damage are spread out over more npcs so you can 'chip down' the incoming damage. You can't with the Githyanki fight. I'm pretty sure a level 5 fighter doesn't get multiattack and have
nintey-six health. One character in this group has more health than the player's party, and one can nearly oneshot a character. I'm fairly sure they even have more than one action, because I'm pretty sure I saw a character multiattack and then attack a second character.
The encounter has too much health and too much damage to be handled without extreme minmax cheesing (and possibly lucky dicerolls) right now.
