How are Priests the best at raid healing when Paladins snipe heals with flash? That was most of my experience with the only raid I did on another server (ZG), is that my heals kept getting sniped by flash-spamming paladins.
Why is this a problem? You're not there to grow your e-peen for topping the healing meters, you're there to keep people alive.

Am I sad that I was #12 in efficient healing on bosses on that raid or that I was #6 in efficient healing on trash? No.

Similar stats there. Sometimes I'm higher on the meters, sometimes lower. It depends on what you do - are you constantly on tank healing duty, are you on decursing duty, or raid-wide healing or a mixture of all three.
See this Raggy fight where I was healing the tanks:

Yeah, woohoo, highest priest on efficient healing. But only because I was spamming GH almost all the time to ensure that the tanks stay up. See how bad my overhealing was in that encounter?
Compare to this Gehennas fight:

Should the healing officer kick me out of the guild because I was easily the "worst" healer on meters? No, because I spent the whole fight cleansing the raid.
You're not in a competition with other healers. The paladins WILL "snipe" your heals all the time. That's fine. It's why I only use H1 and H4 for raid wide healing - even if a rogue has taken more damage. Because one of the paladins will throw a quickie in there but my small H1 will top them up, not cause much overhealing and not spend much mana at all. Paladins are great for quick & small heals and keeping people topped up but priests are there to drop the big heals. No point in competing with paladins, you're wasting mana.
Priority #1 is to keep tanks alive, priority #2 is to have mana at hand so you can do your job. Everything else comes after. Sure you can artificially pad your healing meters, by healing dps standing in fire instead of getting them to move and that kind of crap. But if you want an efficient raid and a guild that can keep going for months and months instead of burning out, you better minimize deaths. Blacklisted had 37 deaths combined in our most recent two Molten Cores. For comparison - nothing against these guilds, just quickly pulled their stats out:
Convulsion 172 deaths
Entitled 122 deaths
Dank Budz Collective 215 deaths
Coalition 56 deaths
Kaamos 239 deaths
Drachensturm 73 deaths
Anyway, I'm getting sidetracked. If everyone uses Luna, all healers can see incoming heals easily and adjust their casts. It takes a little time and practice but once you're used to it, you can easily decide which spell to cast and whether to cancel or not. I save GH for tank healing in the encounters where tanks get heavy damage, H4 otherwise. H1 and H4 for raid healing, depending on how much HP they are missing and if anyone else is healing them. Max FH for emergencies along side PWS.
Hopefully your raid/heal leads and officers are smart enough to take more into consideration than just healing meters. Because otherwise you will never clear the harder raids. MC is easy enough that you can crawl through with hundreds of deaths and spamming flash heal but BWL will demand better teamwork or most healers will go OOM all the time.
