New to P99, questions

[Petraeus]

Hello, I am new to this server (Haven't yet downloaded everything). I played during Kunkark's release as a Mage and Enchanter raiding most Kunark/Velious content.

I am going to be playing casually, maybe 3 hours a few nights a week. I am curious what classes are in demand from a lower level as well as from a raiding aspect when I finally get to raiding level.

I am interested in any of the priest classes, a bard, or an enchanter again. From reading a tad here it looks like Druids don't do much during raids, and Enchanters are basically just buffing/debuffing so that sounds boring. Bards concern me because it seems like twisting nonstop would get very tedious and boring, but I like the versatility they can bring to a group. My brother raided with a Shaman so I liked the buffs, slow, haste etc. they bring to the table. I never mainly healed but in WoW I got into healing and have healed through recent content raiding. I like having SoW/Selos so a cleric kind of turns me off a little. Druid seems to be pointless later since their DoT and DD aren't that strong and they lack in heals. I don't recall, do they buff over other classes in raids? I love the oldschool travel where teleports are needed so I really like the idea of a Druid from that standpoint.

Will I get groups somewhat easily as any of those classes? I read tanks are in demand early on but not really interested as a main. Also what else concerned me was apparently if you aren't hardcore you can't really raid? I have read a tad, so of course I am only getting partial info here. It seems like only the top guilds get to run raids really.

And lastly, I read one topic of a new classic server. Is this server going to get rebooted soon to classic? If so, should I even bother starting before that happens? Of course IF that happens?

Thanks
