Here is what I've noticed, I'll look more deeply into it tonight.
Dragonborn Paladin
Missing Channel Divinity: Divine Mettle (target makes save w/ +3)
Breath attack should be +6 instead of +4
Breath attack should have a type selected (I just chose cold)
Healing Hands says already included, it's not.
Dwarf Fighter
No errors per se, but if you switch the order he gets Dwarven Weapon Training and Power Attack, he becomes easier to play at first level.
Half-elf Cleric
Add an at will power from another class as an encounter power (such as Eyebite)
For ease of use, include the +3 from Healer's Lore in powers Healing Word, Healing Strike, Beacon of Hope, and Cure Light Wounds. Otherwise, people forget.
Missing Gentle Repose and one other ritual.
Halfling Rogue
Positioning Strike should be 1d4+4
Human Wizard
Will defense should be 14
Missing Prestidigitation and Mage Hand
Missing three rituals.
Tiefling Warlord
The updated version seems to have everything in order.
