I think which class(es) do you currently play would be a better option. Top 2 would be best.
Hybrids, don't worry about so much. Even as a hybrid, thrower + 1h shield for example, or cavalry/melee, you play pretty much as one of those classes until forced into a situation where the "hybrid" role makes sense. Throwers + 1h shield are going to Throw until someone gets in too close and they will switch. Cavalry/melee will be cavalry until their pony dies. So pick what you do primarily.
However, if you allow two options and someone only plays a hybrid primarily, they can pick their hybrid options,
