It seems, removing ignite from dot crits does not help much (if at all) with ignite munching.
Last night on Halfus HM I lost 24% of ignite damage, last week I lost 24.5%. But overall ignite damage went down from 2566123 to 1502375 (yes, more then 1 million).
Calculations:
My mastery bonus: 1,36148.
Total direct fire crit damage: 3619554.
Total ignite damage: 1502375.
Expected ignite damage: critDamage*0.4*masteryBonus = 1971180
Ignite damage lost: 1-(1502375/1971180) = 0.24

Yes, I know, it's Halfus is not that good for statistics, but still...
Oh, and it was a real surprise that LB+combustion+impact is that weak now. It ticks for 1900 per target, not 4-7k that I was expecting. I don't know if is new thing or not. May be, just side effect of LB crits not causing ignites anymore. For me, it's a huge nerf for fights like Maloriak, as were is no time to wait for fireball crit on green phase.
