1). Learn maps, you don't need to know every nook and cranny, just learn the high risk lanes. 2). Reevaluate builds. Hunters can be build like a glass canon so resilience is a bit less important. However on titan and warlock, mobility is pretty pointless. If you are not in the mood to let the guns talk, try to find a Subclass and synergise your weapon choices to it with fragments to compliment. 3). Play near cover, most good players never leave themselves too exposed. Is a gunfight not favorable? (Be it outnumbered, or you are way behind on the ttk battle(you didnt land first shot or got ambushed)) reposition. 4). Loadout, there are meta loadouts. There are casual loadouts, there are loadouts that are made it 4 lines of coke. Every weapon you choose, is made with a choice and intention to use and compliment a playstyle. Running double primary? Don't use an auto rifle like a shotgun (unless it's cerberus). Yesterday I had someone run double primary, have an smg and when the opponent was in optimal range of the smg, they refused to use it in favor of a pulse. Make choices, weigh their pros and cons (some weapons don't have pros in crucible, just a list of cons (looking at you rocket assisted sidearms)) 5). There is a difference between projectile and hit scan. But projectile weapons have a fast ttk (but anyone with a bit of rabies will just dodge it). 6). Learn basic ttks, this will help you measure their forgiveness vs yours. Basic rule of thumb, the closer you have to be for optimal ttk, the quicker the ttk. A sidearm, although a primary, is excellent for complimenting a scout for example. 7). Armor mods can help out a lot in crucible, from surges to unflinching. Try to make them compliment your weapon of choice. And the resistances, don't work in crucible. 8). Choosing to use a broom instead of a pool cue is a decision. The enemy of superblack hunters with their estocs, will run their estocs. Crucible has no honor. Choosing to use meta or no meta is entirely up to you, but meta will always be more optimal to lower a skill gap than a non meta loadout. 9). 1v3? Don't fret. Some are very hungry. Just see if you can force a 1v1 against a 1v3 by relocating. Revive control is also very important in modes like trials (control is holding an angle on the revive where the opponent can't revive their fallen teammates) sometimes you just can't help it. 1v3's are just hard to win. 10). Play crucible because you enjoy it, a free mind is more willing to adapt and play than someone who forces themselves through something. In quickplay, screw performance if you are experimenting, screw the meta, screw everything. Grab a loadout and enjoy yourself. -blam!- everything. And if you like the build, use loadout slots to save them. This will help you quick swap to favor certain maps and modes. Hope this helps
