As a healer main, I really don't care if a PLD or a RDM want to play with their toys. When I leveled my PLD to 80, I had to use clemency a lot because some healers couldn't keep up with big pulls. And I know when a healer can't keep up. So I can't blame another PLD for their use of clemency if they have experienced similar difficulties.
Being a healer doesn't mean you have to feel like a special snowflake. Some healers are so precious, it's ridiculous.
