The Necromancer is Standard, the Gladiator is Metamorph. The Necromancer still has her full-respec available, but so far I'm inclined to leave well enough alone. I think the Cyclone Gladiator will be my Delver. As PhroX says, Cyclone makes you immune to Stun, but it seems to also grants you some kind of pseudo-Phasing. He sails right through bad guys while he's doing his dervish thing.
Sorry, I didn't mean to imply that
all Witches or Necromancers are poor at pressing forward, just that mine is. I don't use Meatshield, Feeding Frenzy or Deathmark. Feeding Frenzy just seems like overkill.
More damage?? Sure, what the hell...

I'm thinking about trying out Deathmark. I assume it was intended for targeting Bosses and other thorns in the side, but you could also use it to reroute the whole rugby team when you don't want them to simply follow you. I was also thinking about "Golem Commander" on the Passives web to get another Golem and make it an even 24 Minions (also - "70% increased effect of buffs granted by your golems" -
more damage!).
On Summon Raging Spirit: I think it might be a bit overpowered, although I haven't exactly done a lot of testing.
- They're "fire and forget." The Spirits proceed to whatever point you target and then auto-target and pursue enemies from there, based on their own detection radius (e.g. well off the screen, as far as the player is concerned). It's unclear to me whether mobs attacked by Raging Spirits are pulled by the caster or only by the Raging Spirit.
- You can get up to 20 of them at once. I use Spell Echo so I only need to fire it 10 times.
- They count as Minions, so I presume they get all of the bonuses from the Passives Web. I use Infernal Legion on them, which reduces their lifespan by only a bit (that is, they're clearly benefiting from the Life Regen and Life Leech that my Minions get, offsetting the damage they receive from being on fire). Anyway, their limited lifespan hardly matters, since you can just keep summoning new ones basically forever.
