The synergy is there. Both can invis. Both can summon pets, albeit the Druid one is in no way comparable to a Necromancer's. Druid can chloro the necro and patch heal, Necro can emergency lifetap on top of those heals. If there's a colossal train, Necro can FD and Druid can evac. Both can root/snare when pets break, plus SoW when outdoors. Charm is such a powerful spell; any class that has (even limited) access to it is in no way garbage.

Earthquake? Port to CS, succor across SG, track WW for Tantor. Can also port into South Ro and check on AC spawn. Jet over to Emerald Jungle, then zone into TT and do hunter/forager cycle together. A Warrior isn't needed for any of these targets.

Also, if wanting to complete Coldain shawl and ring quests, Druids are a massive help just by having animal charm and harmony.
