WZ Ranked - difficulty is TOO damn high

Is warzone ranked noticeably difficult af?

I’m currently gold 3 and moving up, but it’s terrible.

I was diamond/crimson in ranked rebirth and I am literally getting shit on in warzone.

I have 4 theories:

• I suck (unlikely bc I do very well on other maps)
• I’m not familiar with the big map
• cheaters
• full squads that have been playing this map for ever.

What’s your experience?
