I play as a Titan Defender and I find that his bubble shield, to me seems too small. It seems good to get a quick break from the onslaught but I need to exit the shield in order to do damage, and by the time enemies enter, they're are already breathing down my neck. So when you're doing the raid and you deploy it, by the time a minotaur is at your shield he could instant kill you. What do you guys think? Still think it's a great game and will continue to play it over and over again. Maybe I'm just playing the defender wrong. :P Edit: I have beaten the raid twice was. Just interested in how people play.
