Just want to agree with everyone here that the blaster damage is significantly lower than it was before the patch, or the enemy got a big buff. I currently cannot complete the Kabal Station Defense quest due to only being able to kill about 20 of the 30 bombers, and that is full out blasters, missles, and EMP. Before the patch this was one of the easier ones for me to complete. The EMP seems weaker as well, doesn't destroy the larger vessels as well as it used to. The Jedi Ships are also much, much harder to destroy. In Kanz Minefield, same problems, plus, as I think someone mentioned earlier, the health bar above several hardpoints seem to have disappeared.
The power conversion blaster fire seems to be the same regardless of which mode I am in. This is true in the level 50 quests as well as the lower level quests on lower level toons, so regardless of which Grade of equipment I am using.
