Anybody tried an all-cleric team?

[Apatheist]

Justicar AoE heals can hit up to 10

This is a good point. It does make us much more useful in bigger fights. Maybe what I need to do is use the video feed function and set up a little mini buff window for each of my toons, so I can see more easily when I need to replace cavalier.

That looks very interesting, Apatheist. Looks like 5 of those should be great for questing and PvP. Then for expert rifts and dungeons, I could switch out one of them to a Justicar role and possibly another one for main heals and support?

This is pretty much what I do. I leveled 4 clerics and a chloro/archon (which I later changed to chloro/lock) but I really didn't like the way the mage sync'd with the clerics, so I leveled a 5th cleric solo and I much prefer it. For instances, I change one of my clerics to Justicar and one to Warden and I haven't found anything I wasn't able to clear yet. 4x DoL is basically a tank cooldown . . . with no cooldown. If you ever get in trouble, pop DoL and the whole group is instantly full again. I much prefer 11 points into Justicar in PvE, because you can always rely on having conviction.

The problem with instant Tyranny is that it really isn't instant. You still have to wait for decays to build. Correct me if I'm wrong, but I'm under the impression that the talent for reducing Tyranny's CD doesn't effect Bound Fate?

It doesn't effect BF, but it reduces the cooldown on tyranny and obliterate. Tyranny you can spam nonstop, but after the first hit, you only have time to build up one decay between GCD's, so subsequent tyranny's hit for a bit less. It's still nice damage, though, for an instant spammable AoE. It's like 300 for tyranny itself plus around 100 per stack of decay (up to 3 max). Decay builds up at around 1 per 1.5 sec.
