Check my review for Emirates from Hyderabad to Dubai! Same thing applies here.. Crew was good but there were service issues. Leg room is still a huge problem for economy class. How do you expect anyone to sit in a stand still position for 14 hours??? And you can't stretch your legs..just by removing 2 rows on either side you can create a great flying experience for all of your passengers...
