Gunslinger. I don't get why people are complaining about tripmines still. There is absolutely NOTHING different about them and I main a Hunter-Gunslinger for CRUCIBLE. My main for PvE is a Warlock. But anyway, people don't check their surroundings. Stick them on walls and they are just as effective. [spoiler]Bungie is stupid because they don't test their nerfs and buffs in Crucible. They didn't correctly fix the tripmine stick. If you throw a tripmine at a guardian, they are counted as a surface. It won't stick but as soon as it hits the ground it'll blow up, still dealing damage.[/spoiler] There's nothing wrong with tripmines. To not use them is just dumb. The other solar grenades are irrelevant.
