I use different variations of Defender practically all the time because Striker is for chumps that need to rely on cheap tactics to win. Not all Titans are pathetic shoulder-charging, lightning grenade-using, Fist of Panic spammers.

Dude I titan smashed one guy dodged like 3 sniper shots, killed 3 people in one life and a sunsinger by a lightning nade and a shoulder charge. Also I am going to sound like a hipster but I used thorn back when it sucked, and I have always slide shot gunned. I also snipe and stuff, just in that situation a shotgun was best suited. Sorry if you hate titans, a lot of us are really stupid, but when you meet a good one like me you will respect them and all classes. FYI I have one of each class. and they are 32 Hunter 34 Warlock 34 Titan.
