Have some questions before I try

Hello,

I just recently quit daoc after playing it a million years and I want to try out Lineage2.

I have read the post about classic servers, will I be able to play them now? If not how long is the wait? Are the classic servers officially supported or some kind of freeshard? If I start playing on "normal" servers will I be completely behind everyone else?

Also: how many gig are the client? I read somewhere "the full client is 16Gb. high5 client is approx 11 Gb." What is this high5 client?

Thanks!
