"Should we drop solo away from our teammates?"
That's the $64,000 question right there. If you're a true rank grinder the answer is always NO. But if the only thing of value this game can offer you is a ranking... with all the twisted psychology and arbitrary standards and flawed judgment that goes into a rank grind... then in my opinion you've already ruined your gaming experience. Why not ruin it some more and own the game instead of letting it own you?
Rant over.
The real answer to the question is, sometimes. If you're on World's Edge and your random jump master is a twelve year old kid who pings streamer building... are you honestly gonna look me in the eye and tell me that you're gonna follow him in because "teams have to stick together?" You already know it's a suicide run, and now you want to double down on his idiocy and get dead right along with him? Think about how ranked works in this game. You would actually be doing him and the squad a favor by dropping solo. Your chances of survival, with or without a teammate, go up if don't drop in that **bleep** hole. If you drop cool and loot for a while in a safe place then you have a chance to replicate his banner and respawn him. Not that it will do you any good. He's already shown you what he's capable of, and what he isn't capable of. But all these things buy you evo and time. And time buys you RP.
Now you're gonna tell me all about how you don't queue up in a shooter just to hide behind rocks. And I'm gonna tell you that that's the game. If you'd rather die in a hopeless early-match fight than patiently wait out the clock and the circle, then that's fine. But don't let's pretend that the game rewards that. It doesn't. And if you need gunplay so desperately that you're willing to die to get it, then you need an arena shooter with unlimited respawns. CoD. Halo. Counterstrike. Valorant. The list is endless. Just don't queue up into a battle royale thinking that it's going to be a safely-paced series of winnable engagements, with no third partying, no strategizing, and no risk. That was last season. Now the adults are back in the room.
