Hello :) Newbie with some questions

Hey peeps, just downloaded the game, having never played the game before trying to figure out what class to play what side and such.
So to help me decide i want to ask these questions

1. Siel/Lumiel which one has the higher amount of players, also what side is the stronger one ?
2. Choosing a class:
Im thinking ranger, but from what i have been reading on forums, they suck ?
Then i thought cleric, always been a fan or healers.
Now im quite the pvp fan, so which one would be the more viable/noob friendly one ?
3. Also what side do i go with does it matter. Asmodian or eloys, which one is the better one depending on server ? ( Does it really matter)
4. If possible could you post some nice guides i could make use of ? ( Ofc ill be lookin for some nice guides myself )

Thx in advance

PS. I ran into this problem reinstall the game aion bin not found something like that ?
Also you will have to excuse the horrible english/grammar not my first language

 

choose siel server then make a warrior class after that take the path of gladiator. it's the easiest class
