Tips for Plat?

@rockyboy1998 You can do it, i reached Diamond in the first split solo queuing. The first legend selection is an aggressive comp, good for pushing teams around the map mostly, so you should have always good aim and good rotation. If you find it difficult you can change and play a bit more passive, adding a caustic or a Wattson or even Gibby instead of lifeline/bloodhound. I'd suggest to avoid using legends such as Mirage, Rampart, Octane, Loba and Bangalore because they are pretty much useless compared to the other legends.

In terms of tips, well make sure that when you engage you end quickly the battle because for sure a 3rd party is coming. If you see that a gunfight is on going for too long just disengage and focus on rotation or play safe for a bit so you can 3rd party someone. If you want you can get 1-2 fights at the start of the game then just go to the last safe and wait because you have already some points and playing aggressively is pointless. Hope this helps you a bit.

Oh Bear in mind that there are still some predators in Platinum that have to grind after the split so lobbies are more difficult than usual now, maybe that's one of the reasons for your struggle.
