It's not that I think the feat is too good, or too powerful. It's power level is actually rather decent, considering the way healing is handled. But there should never be an automatic "I must have this" ability for anybody. If you make a healer of any kind, you will be taking the Healer's Touch feat, because it's such an obvious choice for any healer.
It's not too powerful, but it's just good enough to be something that will always show up, no matter what game you're in, as long as there's a healer. And that's boring.
Yes, it's a risk.
What I meant to say is, that while I can definitely see everyone wanting to play a healer looking at that feat and think "it's a must-have for me", then after playing the game for a while it might turn out that you really didn't need it if the campaign is not particularly deadly and fast-paced, because the normal healing capabilities + the short/long rest rules already suffice.
IMXP the "must-have" abilities tend to be more under the attention of gamers who spend most of their time building characters rather than playing the game.
