Long story short, if you are a carry you don't take heal. Your job is dishing out damage while living.
With the current meta, you take cleanse, ignite or barrier based on the oposing teams comp, your comps peel ability and your playstyle.
Edit: You don't take heal because you will likely be the target of an ignite when you need it.
