Unfortunately I don't get paid, I just have a lot of time on my hands.
I'm not saying that the arena is perfect, all I'm saying is that people actually have to work for it. I farm dragon several nights a week with my auto runs while i sleep. My Arbiter has gone from 305 speed to 312 speed in the few months I've had her. This game is designed to be a slow grind, if it wasn't people would get to end game and then get bored way too fast.
Kind of like saying Joe Bloggs who has a minimum wage job at $15 per hour can also join the millionaires' club if he religiously works 40 hours per week 52 weeks per year and equally religiously saves 20% of his sub poverty level wage.
1,000,000/3/40/52 = 160
Oh look, he has to live to 160 years. But no doubt he's has a rich, fulfilling and most importantly a FUN life, heh?
Oh and btw, I do so admire your deft and skillful, not to mention FUN, use of autoclickers while you sleep. Now that's what I call "working for it" indeed!
