I play mostly PvE and I don't see a need for Sunbreakers. Most people find defender extremely helpful in activities. You're a spigot for orbs, an extra overshield and saftey to others in danger, you can still titan skate with defender, you can make guns more powerful upon command, you can be almost invulnerable inside armor of light...all the more reason defender is the masterrace of Titans. [spoiler]Btw, I'm pretty sure my titan is the sexiest guardian in the last city [i]and[/i] she helps people. Who doesn't want a smoking hot awoken chick defending you?[/spoiler]
