New to p99 what class is most needed?

[Kaakkarott]

As the title suggest I am new to Project 99 and wanted to know what class is most needed for grouping up. Also raids? About me- I am a veteran player of all TLPs but I wanted to experience my original EQ days. I received EQ for Christmas in 99 and played until 04. I then picked the game up again in 2017. Now I wish to play the 99. I am currently on the green server but can change easily for the right game play. With that said, what are the classes missing from the daily grind groups, what is needed? What classes are missing from the raids? I have played them all and epiced all toons (-Rog). Just looking to dive in to a useful class. And if all else fails I'll just return to my roots and play a necro. Thanks and hope to see you out there!
