Which is why I said Singes are only useful with Heavyweight. The Singe itself gives a minuscule buff, but it stacks multiplicatively with Heavyweight so it’s just enough to make it noticeable. Running an Arc Secondary this week over a Solar one makes very little difference, and isn’t worth leaving over. Even using the wrong flavor of Heavy doesn’t matter too much, since Heavyweight is doing most of the lifting. The only thing that you can feel are Grenades, but like I said you can’t blame people for using the wrong subclass when Bungie made challenges to directly contradict the modifiers.
