Where is it okay to be dumb?
The problem with healing in general in raids is, it’s not useful on every boss (since some of those mechanics one can not fail and live to tell) and other classes do it better mostly (healing druid, minstrel mesmer and healing tempest). Thus you are fullfillng a role that is not always needed and revenant is inherently bad at multitasking (unlike say a healing druid who can opt to wear condi gear when less healing is fine).
You are essentially competing for that 1 pure healer spot (2 on matthias if people want to play it safe) with other classes that provide similar required amount of healing while they provide other benefits as well. The best chance to keep playing the build in raids would be to join a casual fixed raid and have the other 9 people adapt to your build.
WvW zerg might be interesting if you adapt your build to incorporate resistance uptime.
Dungeons would likely work too.
Fractals can work if the group is aware of what role you are fullfilling. Again though, a dedicated healer is not actually needed here.
of raid bosses, your build might work for more chaotic attempts at Cairn (especially since you could double as kiter in addition to being the third healer). The general problem is, again, what was mentioned already – more experienced groups might not need a third healer at all (and for primary healer roles druid is better due to the GotL buff).

Find a partner that likes to DPS. There are all sorts of high-level fractals that can be two-personed, particularly if one is a healer.
For a while, a friend (and later, myself) ran a similar burst heal druid. My version could heal through most forms of agony, poison, and what not, and keep anyone alive who was able to remain stacked. I stopped running it when people learned to keep themselves alive, so I could afford to swap to more DPS/utility. (Also some people have trouble with stacking when there’s social awkwardness.)
tl;dr static groups are best for useful, off-meta builds.
(or set up your own training runs; then you can choose to be the healer)
I let members of my guild run off-meta stuff like healer Herald periodically for random bosses we’re extremely confident on. It keeps things interesting, lets players try new things, and doesn’t otherwise cause any problems. Consider also running the healer Herald as flak kiter for Sabetha; it’s pretty fun there! I also find it very effective at Matthias. That said, don’t expect it to fly in any pub that dares label itself “experienced” because they’re only interested in the meta of the meta.
P.S. Healer Minstrel’s Herald is totally awesome in WvW. I use mine there when I run out of raids to beat in a week.
