i know i probably shouldnt say this but.... i'm tired of saying the same things to ppl when they look for servers so sometimes i dont even bother anymore >_> so, FOR THE LAST TIME: i will write everyhting i've said in the past about picking a server. I dont blame the ppl who asked though ^^ u probably didnt realize :)
so... (from "Questions." by DarkAbyss)

"i'll try not to mention as many servers as possible, but...

maybe come bk to the server that u used to play on, but if that isnt possible i think there are three things important about choosing a server (theres probs a lot more if u look into it):

1. Prices! ( for e.g. Aries server is said to be overpriced )
2. People! ( Friendly, active etc. ;) or.. IS THERE ANY PPL THERE AT ALL?! :D )
3. TIME!! ( ppl usually forget this one, but its actually one of the most important ones!! EU or US ^^ this can influence point no. 2, obviously cuz of time-zones. )

im guessing u get a lot of these posts from ppl, so ill try and name some if u rly want me too >_>

if any1 has more info, pls tell me!! Disclaimer: this is half mine half friends opinion so pls dont be offended! correct me if im wrong ^^ i mainly play on Libra and used to play on Virgo, but i dont mean to be bias towards those

P.S like Sandz said, u can use fb or THIS VERY DB!! :) there are a lot of ppl with their chars in their sigs :)"

Next 1 from "Starting Gameplay" like below :

"If it is because of ur internet, try a bit less populated server (like kev said). consider also the features that you would like in the server, like the people, the prices (if u dont want to make ur own eq) and maybe even the 'friendliness' of people (like how willing they are to team up/help you). u can also switch servers if u dont like it on one, but make that ur last resort to prevent u from having weak characters everywhere :)"

THERE A LOT MORE! but i just couldnt find it >.> now before the hate comes.. the reason y i cant exactly leave libra:
(from "Starring gameplay" by Dark/Sriker. It doomed on me 1 day that they might be 1 and the same XD)

"I think that if u play solo, u cant really get anywhere unless u devote ur whole life to it -.- we all agree on that, right? so we all know everyone needs friends :) i think that as long as u can find some1 to play with, the server isnt dead. It might be hard to find those ppl on Libra (and the 'populars' on world arent the kindest either :( ) but u can still find nice people. I started playing on Libra, and I'm still proud of my levels. As i said earlier I have a char on Leo who got the same level as my main on Libra, but I'm not exactly 'proud' of her :/ Im too bonded with her so i cant just ditch Libra XD"

Hope this helps! and i have formed this opinion by actually PLAYING on those servers (except the ones that i said i didnt) so maybe i just missed or came on at the wrong time :/ and i would love to have some friends on other servers who i could do instances with for example, just for fun ^^
