WHM: Relic+1 vs AF2

[Sziadan]

If you think a small boost in the heal is worth more than more defense then by all means, go ahead and get Relic+1.
The AF2 chest is better than the Allagan chest, the Cleric chest gives you spell speed instead of Determination which the Allagan one gives.

Sebyos, 910 heals vs 950 heals isn't pathetic. Keep in mind that he's able to take a bit more damage than you because of that, a dead healer is a worthless healer.
I personally went for the AF2 chest and the AF2 head, I will be getting the Relic+1 next though since it's now the biggest upgrade for me.

For a DPS, the relic +1 might be worth going for first, but it's questionable if the same goes for healers and tanks.
