Probably 90 days tops if I only played that account, but I guarantee we will never know :)

Don't want to start an account just to test that, Quinn style?

I started playing at the end of october 2020 and got arbiter in july 2021.

Much of that was struggling with arena which was a bit more difficult at the time. I didnt really play much the first few months either, but still i imagine i took a lot longer than players take today

I don't have her... yet. 

I'm currently on day 125 and sitting @ quest 41/60. (If the *&@% potion keeps opened in the same order as the quest I'd be 4 days closer.) Right now, I'm waiting on the Force Keep to open Friday then the Void keep to open Sunday. Already have my Force & Void 60s ready to ascend to 6*. 

My only time hurdle will be the 200 Classic Arena wins. I'm currently in Gold 5 Arena w/ around 50 arena refills in the bank and I've thought about putting up a 1-man Defense to fall in the brackets in order to speed this part up but I'm honestly not in that much of a hurry. I know Arbiter is good but with the champions I already have I don't feel like she is going to be "account changing". 

After that it's smooth sailing. I can already clear all 3 of the stage 20 dungeons on auto and 2 key (so close to 1 keying) Nightmare CB daily so those 3 missions won't be an issue.  

I don't understand the "hurdle", can't u just fight solo defenses in G5? Probably more in G5 than g1 to g4, no?

87 days. With that I WFH and have the most ridiculous rolling schedule so turning farming on auto and going back to work.  Its doable but but yesterday when I burned gems to finish the two Demon Lord tasks really openly pissed my Clan Leader off like I had no idea what I was doing. 

Keep chipping away at that goal. You'll get there when you get there.
