Being here, and supporting (spending as I did in the past) are two different things. However to answer your question. I stay because of the people that I consider friends, who haven't quit yet.
80 to 300b was worse than 300b to 1t as in there were no level upgrades in t7 which made the going to 300b a nightmare and a he'll lotta gap but now their are level upgrades so it doesn't matter much as it is 600b-1t
I was at 44 T8 level 1 After upgrade to 7 T9 level 1 ( and one new dorm opened ) my plunder drop by 6m Sent feedback , ATA replied that " It's recommend to upgrade new tier to at least level2 so you can start to see plunder go up because the first level of the high tier is weaker then top level of the previous tier" Idk cry or laugh lol, my T8 all are level 1, how could it stronger T9 level1 ?!? Just to share so you can consider upgrade or not.
