Returning and want to start new

Hey there,

I recently thought of returning to Lineage 2. I've been absent for some months (or even or year or more) and I don't really remember my old account information (not this one, the one my mainchar was on).

I want to start new and since I got an email that Zaken got newly launched I thought that now will be a good time.

So I got a couple of questions. First off:
How many people are daily online on the Zaken server?
Is it worth starting there or better start a new char on either Chronos or Naia?
Is it true, that most people switched to ****** or is that still the same false-spread propagada as it was 2 years ago?
What class should I start if I don't have any Buffer / Money / Clan to level up fast and (mostly) solo? Summoner? Archer? Warrior? Mage probably?
Can the above mentioned class be good in PvP? :P I don't want to be totally useless in later levels ( > 85).
What is the best way to level? Still going to 65 with the quest line and do Hellmann? RB camp later on?

Thanks a lot in advance!
