Hello i want to start playing daoc agian and whas thinking of joining mid
im just not sure witch class i want for a start class what classes are most needet on mid both raid and pvp wise to make it easier to get a temp

In RvR, the essential classes these days are:
Healer
Shaman
Berserker
Warrior

Several groups play with runemaster and skald as well. I'd stay clear from all the other classes. Getting a decent template for lvl 50 should not be a major issue with the money you will make through leveling up; otherwise you can join a few Tajendi raids or similar until you get a few drops that you can sell for a few plats. Some people suggest to skill up tailoring, which will give you the ability to salavage drops and sell the raw materials with a good profit (ask ingame for specifics).

Zerker, without a doubt.

Healer or Shaman, and you'll always get grouped. Even funny in RvR, it's not about just healing people
