I’ll just chime in as a fellow “drop at less than a moment’s notice” player and suggest you add a Paladin as a third to shaman/Necro so you have some sort of rez. When you are on that ‘have to go now’ schedule having a rez In group is big; as is a porter or corpse summoner. You seem to have most of the necessities locked in, so consider giving yourself a rez, a few more buffs and a plate tank. If you don’t like it, can the Paladin when you hit level 30 or something, but you will have it if/when you want it. And with your trio, the Paladin will be fine in Velious gear/cultural armor for basic pop camps.
