This is how I've seen it through trials; Warlock Self Res Great for surprise attacks, having scorch Melee OHK, spamming fire bolt nades & if your team mate is the last left most of the time they'll run off to kill him so res & get your team mate up then get them when they've separated. Fire Bolt nades combined with the DOT perk can make quick work or enemies, having 2 firebolt nades can drop an enemy of both hit. Nova Bomb Only use I've found for this is when a team is right by eachother & having the tracking & split nova bombs can take them all out if they've bunched up together. The AoE nades can block of certain paths giving you time to escape or revive, the tracking nades are great if you wanna flush an enemy from their position. Hunter Blade dancer Only good when enemies are close together, with level advantages on they become much weaker in blade-dancer. Turning Invis during the super can help you get the jump on them though so it's not that bad. Not sure which nades the best since I'm not a fan of using my blade-dancer. Golden gun Having 4 shots with symbiote can easily end games if you have a team of hunters as with GG range & OHK, it makes most people who are at a distance start to panic that there is a GG around. Trip mine nades are fantastic, throw them behind, under, on and enemy and it's instant kill. Great way to set traps for people rushing you and not paying attention. Titan. Defender. Really, the only good the bubble can do is keep certain spots held down, once you're surrounded though you'll have to either come out or wait till the bubble pops and you'll be sitting ducks. It's good for the heavy round & capture the zone. Striker. FoH is pre much the same as voidwalker. Arc bolt grenades. Easily the best nades in trials. A trick you can use is change over to gear/super you aren't using then switch back at the final second so if they checked you guys out they won't expect a change.
