Second Wind is a terrible ability and either needs redesigned or outright removed.

Great. Then tell those people who want to go through MSQ as a healer "You only need to suffer through the MSQ once every expansion, which can take upwards to 20 hours from beating up monsters alone or doing some solo instances. It's not a big deal because you're only doing it once!" I love to see how many people would say "Yeah, that's perfectly fine by me! I don't mind pressing 2 buttons in every expansion AND patch cycle until I get to group content! There's no way I wouldn't just swap roles instead because I found it too boring!"

tbh even if we only go through the experience once and all that you said, we're still going to be pressing the same button even past that in group instances. Even if we do have to heal, so what? Imagine a Bard with only the songs and Bloodletter. That's how it feels to play healer. Sure you press other buttons, but for the most part you're literally just pressing the same one/two.
