Depends on what you mean by "Making the game easier" because a lot of quality of life stuff does just that and it helps people progress faster so I'd say 0% is hyperbolic.
Also there's a failure here to realize that people are more likely to spend on a game they're enjoying, if you have to PAY to make the game fun in the first place then people won't stay so "F2P goggles" is a bit ignorant (and assumptive).
I'm not gonna spend much time on this repetitve point "It's not a problem for me therefor it's not a problem" because it's invalid and makes it sound like your experience is everyone's experience, but I will point out that mathmatically the Daily Arena and the Monthly Arena requirements line up. The daily Campaign and the Monthly aren't even in the same ballpark.
Finally, I get that the majority of your feedback is saying what Devs SHOULDN'T do but the track record on that isn't favorable (See recent LA balancing)
EDIT: Speaking of LA Balacing, I wanted to mention that there's been next to zero complaints about unfair matchups in the Discord Cluster for a few weeks now since the new patch went live. I wanted to give props to the Moderators for passing along the feedback from Moored's thread (tho I'm sure it was many other threads and sources that led to it)
