Some questions before deciding to jump into dofus

Hello there, I have played dofus when it was beta then, going up to level 42(?) I was a feca then. However after that, I stopped and a year ago, I hopped back into dofus. Things have really changed. Made a cra, played in f2p for awhile. Realized it was overrun by bots, got bored, quit.

Well now, I am deciding whether I am ready for dofus, with p2p of course. So basically here are some questions I have.

1)Whats the difference in terms of community/population and stuff in the different servers? I am a english speaking only user. Currently living in Singapore(GMT+8). So what would be a good server to start in?

2)I'm rather confused about the 1.2x and 2.x servers, is there a difference? If so, which would be a good one for me start in.

3)I have read and heard about how a single player with multi-accounts can go through the game by himself, does it make a big difference? Or is it easy to get groups and good guilds to play with?

4)Which class! Currently Sac has really caught my attention, I am personally finding a class that I can play decently in groups, and of course, hoping to find a group of people/guild that I can start in and really grasp the basic and knowleadge about the game while having a fun time.

5)Lastly, if all goes well, I would most likely start up with a 1month sub, so which sub item should I pick?

Thanks in advance for your patience and if a kind/fun guild that is willing to pick me up, hook me up! I'm living in (GMT+8) So hopfully it would be one that doesn't make me feel like I'm playing alone when I'm online. Cheers!
