Normally I don't wave the "25-man is harder than 10-man" flag too much, however Heroic Ultraxion is very easy in 10-man. There are no DPS problems (if you're decent) and healing it is a joke. Restoration Druids could solo heal 10-man Heroic Ragnaros as well (my guildmate has done it). I'm not trying to start a flame war here but, solo healing Heroic Ultraxion 10-man really is not impressive. Not because of Holy Paladins being overpowered, but a poorly designed fight resulting in zero DPS or healing requirements.
