Why are Guardian Rank 3 and 4 players so prominent, especially in Competitive?

In most of my recent Crucible games across multiple modes including Competitive, I've seen nothing but low Guardian Rank people doing way better than they should, having popular weapons like Spare Rations, while also either having near 300 light, or over 500.

What has caused this trend, and why does it feel so suspicious when they're dominating Competitive? Something feels genuinely off, especially when GR 3 and 4 are easy to finish.
