Balance of the undeads for necromancer class is pretty bad. Summon undead sucks, even phantoms with +8 undead control die FAST. For all that mana, I'd rather just frostbolt. Banshees are completely worthless now, a brilliant gift for any tri 40 necromancer. And undead control eq can only be worn when you summon undead, doesn't seem right.
What Tony DIDN'T want for undeads is the best use for them, and that's in groups. When I asked him why do undeads steal exp from groups, his reply was "because I don't want a group with an army of undead behind them".
Here's my thoughts on the subject:
1: More than double the hit points for summoned undead.
2: Half the damage the undead do.
3: Make it so UC eq has to be worn at all times or the undead control affects go away.
4: Make the UC have ac, and/or add more UC with ac +stats.
5: Summoned mobs attack other summoned mobs when grouped with another player.
6: Give banshees hp more than wraiths.
And another thought, avatars should be able to cast all supplicants, or at least all those up to tri40

. Avatar 40 can't even cast a kachina
