I'm just going to say this in the most respectful way possible. If you aren't paid to be arguing then you shouldn't be when nobody asked your opinion. Nobody came here to argue with the community manager when they're just describing their negative experiences in game and how they feel.
Just so we're clear though if you wanted to insert your opinion when those arguments are best to be had amongst players not associated with plarium let me explain why your opinion is meaningless.
First everyone associated with plarium, whatever the opinion is, has the same opinion why mech arena isn't pay to win. What is considered pay to win is partially subjective. While not exactly it's a matter of what can be tolerated. You wouldn't be know that if the only people you talked to was plarium employees.
Second the line between what is and isn't acceptable is just below whatever plarium is doing at the time. In other words, you move the goalposts.
Back just after launch when everything was available for in game resources on the progress path. The matchmaking was purely XP based so as f2p there was a high chance you got put against p2p, who had a significant advantage against the much lower power f2p. But every item could be obtained with in game resources so the seemingly official opinion was it's not p2w because that.
In those brief windows when all META items are available for in game resources in the gear hub the argument becomes mech arena isn't pay to win because you can obtain everything META for in game resources.
When that changes, like now that deathwalker is the best mech in the game better than surge and Eclipse your argument is the current opinion which most items are available for in game resources in gear hub.
So again stop cause nobody even cares what you think in this regard. You're welcome to describe your own experiences. That is if you still truly play the game. Say something that goes like "sorry you feel this way [...]". But nobody wanted your opinion. That information is worthless.
