30 seconds? I must be introduced to these PUGs for they can teach me much as my average platinum life is 3 seconds.
Yeah, maybe it is closer to 3, lol (been awhile since I pugged plat).
Rest assured, once you have a healthy supply of lvl IV ammo and cyclonics, your platinum life will be extended. Of course, it is more important to know the in's and out's of gameplay mechanics. Learn how to stagger different enemies and learn when to/not to attack them. Learn sync kill mechanics, and how to dodge/shoot when recovering from a revive. Learn to evade efficiently and develop a flow of transition from one right hand advantage spot to the next. Obviously learn to quick vault cover, reload cancel, and take hard cover to reduce damage taken... the list goes on forever, lol - but the more you know, the more confident you will be. Confidence leads to intelligent aggression, intelligent aggression leads to things dying quickly, and things dying quickly leads to you not dying as much.
Well that's the theory anyways.
