Man DICE royally fucked up Defuse. You constantly go into spectator mode on yourself, you still maintain control but you get a big fat "Spectating <name>" and some mouse keys to change view. Sometimes it starts spectating other players when you are still alive and it keeps flashing black for a second like it goes into spectator mode but doesn't.
All you read in chat is "I CAN'T SPAWN!?", "I'm frozen", "WHAT IS GOING ON?!"
You can't even write when dead!! which is murder for a mode like this. I was so stoked for this mode and knowing DICE, it'll take 6 months before they release a patch for it.
Oh and it apparently does a poor job at saving points. Played a round, levelled up to 6. Next round I was 5 again, completed that round and levelled up to 6 again. According to BL I'm 5 points off 6.
