My tree is one of the main healers for my guild. Our other regular raid healers are a holy pally, a shammy, and a priest. Everyone thinks I'm the best healer we have, but that's mainly because I put out really big numbers. If we take three healers into a 10-man, I won't just top the meter, I'll do twice as much as the second.
I'm worried that this has become something of a self-perpetuating cycle. The other healers tell me not to decurse or abolish poison, they'll take care of that. They think it would be more optimal for one of them to be out of active healing than to take me out. However, that just puts me way up on the meter again, and the perception continues. Don't get me wrong - I'd take a poison cleansing totem over me having to click abolish onto every raid member, but if it comes down between me and the pally for decursing, I don't want to make sub-optimal choices based on just the meter readouts.
