have a XBOX 360 and spent 10 hours just on skolas boss. We killed him twice , dismantled mines and was denied the win. ALSO was close to finishing him off at least 30 other times but there is so much lag getting into inventory to load weapon synth. ALSO most of the time we were preparing to start the last Boss waiting for the 5 min. cool downs as a result of death while in the inventory using a synth, only to find you have to load another because it didn't load. Other annoying glitches happen as well, such as no servitors after the first one appeared, no wolf packs to Gally rockets. I don't like the cooldowns for one thing, but its part of the game. There should be an added feature where pressing X reloads weapon ( already there) ,then X again to reload synth
