First off, let me just say that Clerics are pretty bomb, even post OM-fix. We were one of the first guilds to get overhauled and improved in a big way as part of 3.0. That said, the communes feel unfinished, and I think many clerics would agree with me here. Let me start with one to kick and to change.
Eluned's second commune - I don't know anyone who uses this, ever.
Hodierna's is good but the fact it can only be used when you already have an active bleeder makes it too little too late since it requires a bit of work and two existing and functioning arms/hands unless you have a lighter. It would be a nice improvement, IMO to change it to provide some bleeding reduction preemptively. Maybe it could be changed to two one-handed items - say holy water and blessed wine - fitting for cleric blood-related magic.
Now here's where I think we could get a little more inventive....
Commune Faenella: A commune to provide protection of a corpse from disruption by a necromancer. I doubt this would be used often, but it would play into the lore well and hey, it's better than fish feet or something. You would require a feather from the cleric shop or a feather from a Flames resurrection (if those still drop? I haven't seen one in forever).
Commune Trothfang: As clerics lack any weapon skill, accuracy, or offensive factor buff spells, it would be nice if we could perhaps get something that would perhaps increase damage with melee weapons but with some kind of cost. There are a lot of ways this could work, but one off the beaten path idea I had is that you would need to give yourself a moderate ext/int bleeder right on your left hand (cannot tend yourself now). You get a damage amplifier until you've killed X things (2X for undead) where X is half your circles.
Commune Firulf: Something to help you locate dead people. This would be a pretty high circle quest. Window of maybe 3 minutes after someone's died, but you get to see their room name or nearest city?
Extra ideas - how about a Rakash and Prydaen only commune? Tenemlor would be a good one for the no-touchy-dead-body idea I had, but I wouldn't want that to be racially isolated.
