Though the Sunsinger ability Solar Wind can be great for dealing with idlers as has already been mentioned, it can also be employed by trolls to cause havoc during the middle of an intense gunfight. If you're unlucky enough to have a troll in your fireteam, they can use the ability to push you out of cover during battles, and also to screw up your aim by moving you around. It can be incredibly annoying during some of the game's more intense fights later in the game, and though it's easily solved if you're running the fireteam (by just kicking them out of it), it's still a tremendous annoyance (and of course, you'll then be one man down). In addition, if you're fighting near a perilous cliff edge, don't put it past one of these trolls to try and push you off the edge, though in honesty you'd have to be pretty absent-minded and/or unlucky not to realise this before the fateful moment happens.
