What's the problem with Paladin?

[AsteriaStarfall]

Weakest AoE Threat (A huge issue for A2S because flash doesn't hurt anything and CoS barely hurts a thing. Why is there no circle slash!?)

Just started playing pally this past couple weeks. This was the first thing i noticed when leveling. I was totally surprised that no damage AoE ability was present until level 50. Hell the other tanks get AoE abilities at lvl 12, why those would not be cross class able is beyond me. I like the look of paladin, and will continue to play it. I however do not raid savage, so that's probably best for me.
Seriously, just my mind was blown that there were no AoE dps spells before level 50, and then the one at 50 has a medium CD.

If i was to redesign the spell: 5 second CD, and uses mana. That way it would balance out the quicker recasts, Potency of 175, and learned at lvl 20
