Not being able to natural one of an item from the pve rounds is pretty bad. This is in no way an issue with the game. You should not be able to narutal one of an item from the PVE round.

I was trying Diana carry, and I couldn't get a Negatron cloak to complete a qss, or even a single belt to make a Trap Claw. These are not Diana items, and not necessary to place top 2.

I don't see how that type of thing is good from a competitive standpoint since you are just beholden to rng even though statistically speaking, I should have been able to get one negatron cloak or belt that game. But nope, rng.

RNG is not the issue - your lack of understanding on how to execute was the issue. This is ALSO why it's not bad thing from a competitive standpoint, because in competitions the people who succeed are often the ones with the better understanding of what they're competing at.

And also, not being able to counter the overpowered cc in the game unless you build a qss or trap claw is pretty bad.

CC isn't overpowered, you just like understanding of how to play the game. If you're unable to get proper items to avoid CC you can still position your units to minimize the impact of it or PIVOT your comp so that you can better deal with the damage that is coming out during that CC.

There, I've addressed all your points. All that possibly could have been gotten from your whiney post and all of it just comes down to YOUR PERSONAL LACK OF UNDERSTANDING and nothing to do with RNG that you claim makes the game "unmagical"
