HA vs Nexus, some Nexuses have higher stats?

[Urielparadox]

Except nexus phase alone takes 11 hour at they very least if you have 8 people farming non stop and the bonus is always a fast fight, reality is closer to 30hrs of just fighting, ignoring getting and replacing members and tracking down light bonus since the spreadsheet is almost nvr updated). atma phases takes on avg 20hrs, books take 30hrs(1500 myth +completion time), and novus takes 30+hrs(75 alex, 800 myth/200seals, really this is closer to 50hrs).These are all assuming insta ques, not waiting 7hrs+ for fates(like most people do) and completely ignoring the 5-9 million in gil thats another 30-70 hrs, if you want to make a determination based weapons. This is not avg this is best case scenario. A group that spends 3 month learning t9 to clear it is taking wayyyyyyy to long. And I said only 1 run because we are using best case scenario. Just like you can go 20 runs of T9 and never see your weapon, I spent over 40 hrs collecting all 12 atma, and had 2 fates that took 7hrs to spawn, luckily my job at the time allowed me to do this. Even now when I'm collecting atma set number 2 it's been 200 fates since my last atma and fates/hrs are dramaticly lower due to no one else doing them or people killing random fates instead of working together. 30hrs for a nexus 1000% impossible. However I can and will start t9 as soon as I move, and i will have it cleared in under 3 weeks. I'm not talking about a group thats been goingno for months. I'm talking about an individual who starts now, will spend 100+hrs, unless super lucky then maybe 70(when atma first came out not now)getting nexus, where as a skilled player can join a group already on t9, or t9 practicing and clear it in a matter of days
