I think when you pull out a win, and the mmr is at or above the level of all the raiders in the group, a blueprint should drop. If the win is a 'gimme' or its a loss, the chance to drop a blueprint should be much lower.

Yeah Doldren would still be in danger even if his mechanic worked as advertized and allowed him to grab-kill whatever elite he snuck up on. He can jump into action, but can't disengage very safely. Other aliens are long range, he is very very close range, like Lycus or Alicia but without the health, regen, or shield to keep him alive.

Currently he is useless in all PvE scenarios. I have really and truly tried to give him a chance using all of his weapons, and all I am is a liability to the team no matter how hard I try. So I equip his support cards in an effort to at least do a little bit of help.

If you want high melee damage, there's better characters for that. If you want high damage headshots, there's better characters for that. No matter what role you are trying to fill, there's better choices for what he can do. His current strength is only exploiting the natural deficiency in human reflexes and attention focus, and MSE has removed all of this weakness from enemy AI. I have appeared behind enemies that are literally busy with other things, like shooting at or dodging other raider's attacks, and they will counter whatever I do without fail. Since this update they seem to at least take a punch before reacting, but grabs don't work, and punching is still risky at high MMR because half the time I go for melee, the AI will hit back twice and then shoot, always resulting in a down...the mooks' counter-melee is faster than Raider melee, so they can counter you between strikes. They play by totally different rules which continues to be BS.
