The primary redeeming quality that I can see for the Raven is its Armor Regeneration of +5%. Fully upgraded, this will give your Raven a full +9% of regen. Not in the class of the green eagles 14%, but not too shabby. Regeneration is one of the most powerful features that you can have in this game and the M-11 current offers the best available in this category. Armor upgrade is best in class except for the limited edition Dragon and, of course, the green eagle. Overall, a good defense class plane. If you are going to pay coins for a defense plane, I would recommend this above the rest, solely due to the armor regen stats..
