We recognize that some builds which currently use Trail of Cinders will no longer be viable once this bug is fixed. Ultimately, we want to continue to provide players with more build options and ways to feel creative with their skill/gear selections, but not at the expense of going against our design goals or creating situations which can encourage players to limit themselves defensively.
In this case, Discipline-based skills were never intended to trump Hatred-based skills when it comes to dealing damage. Instead, Discipline was designed to be something you build up and save to use defensively, or to provide utility in addition to dealing damage. Allowing Trail of Cinders to remain in its current form goes against this philosophy, and in addition creates risky scenarios for players (after all, if you’re incentivized to spend all your Discipline doing damage, it won’t be available when you need it to keep yourself alive with skills like Smoke Screen or Shadow Power).
We don't yet have a date for when 1.0.5 will be released, but we'll provide more information as the development process continues. We'll also update this thread with a reminder once we're close to releasing the patch.
