All consults (including Bain) in the Middle-East are growing very rapidly and have roots that are less than a decade old. Thus certain amount of ups & downs are natural. Instead of reading 3 year old discussions the best solution is to get the latest perspective. I recommend to reach out to Bain people you know - and ask them.
