Well the thing is, they won't be great because rarely they see a good player around so for them it's simple 'a hack' since it's a huge difference in a gameplay. When I started to play, there was a lot of random good players around so it was easier for me to figure out how it is possible without accusing for hacking other ppl. It's not that they don't have potencial, just over years old player base is gone. Last big update was 2014 and 2017 is almost over xD I really doubt many would return, even if lag is on minimum.Simple because there is nothing new.
Also I've noticed they complain how 'classes are expensive' so maybe this player base is just used on games that they play in some short period and earn almost everything. FFT takes a lot of time to be really good at something (or even all classes), to earn them without buying cash boost and to get max rank or u gonna spend over 6h daily in FFT or again xp boost (also no one plays space stat and that gives 5xp more) to get it in like less in a year.
