offensively. anytime there's a spawn point or choke point, there goes my bubble. works great on that entire pile of knights outside the left door for Deathsinger -- wizard goes down, i pop one right there, bring down the shrieker, and everyone heads right to take her down. one popped in the middle of that hallway is great as well, keeps some of the knights and acolytes milling around while you take Ir Yut down. and of course, boomers if that's your gameplan for Crota himself. with HoS-14, i've found it's no longer about where i can pop it so that all of the team can get to it, it's where i can pop it to -blam!- up the enemy's day most spectacularly.
