Since the design of Ignite doesn’t allow us to resolve munching (defined as multiple simultaneous crits that fail to properly proc Ignite) directly, we’re thinking about a solution that would instead prevent Ignite from proc’ing on periodic crits. This might be a minor dps loss, but possibly no dps loss at all since it would stop most cases of munching.
If it turned out to be a dps loss, we could compensate for it elsewhere. You're likely to see some experimenting in future patch PTRs. This is a pretty good example of something we can't hotfix, or rather wouldn't try. It’s the kind of change that would likely have unpredictable side-effects.
