At pilot skill 6 it begs the question why aren't you spending a single point more to purchase Miranda Doni for your squad? For an extra point you gain an incredible ability but also a massive pilot skill increase.
Esege's ability isn't horrible (would be better if tokens could be used on the defensive side as well), but I don't like stripping the K-Wing of defence/offence but it is a case by case analysis. The pilot however can used Advanced SLAM to SLAM into a position, then take a focus action allowing friendly ships to take it. Of course this then creates some synergy between any crew capable of altering or manipulating focus tokens (Jan Ors, Recon Specialist, Rey).
