i personally think that the backburner should still add health. not much i thought 50 was wayyy overpowered and somewhat ignorant on the dev's part. but 15 or so makes sense. crits from behind do not make up for the power you lose without the compression blast. last night i was playing tf2 and the other team would do nothing but do uber pushes and the pyros using compression blast saved my sg plenty of times as well as being the main factor to holding our position. but then again it might be a situational thing.
