Flashbang? Yeah, not a bad choice. But, it's no super bubble. As for orb generation, you have a ton of options with the defender. If you want, you could make your bubble drop orbs when it takes damage, you can drop orbs when you get heavy weapon kills. Plus if you're doing top end content like hardmode raids, you should not be putting yourself in melee range of anything, so fist of havoc is bad news. I guess striker is OK for low level easy content, but then again, so is anything. Just go defender. You can't out argue it's utility to a raid or crucible team.

Philosophy? Lol
