Fire / FFB - Glyph of Living Bomb

It is affected by all damage and crit talents except Hot Streak and the 6% crit of World in Flames. Burnout, CSD, 4T7 crit modifiers apply, but there is no mana cost/refund from Burnout/Master of Elements. Ignite is applied, causing more rolling and stuttering, but proper testing show no statistically significant gains or losses.
It interacts with Combustion, i.e. it increases but also consumes charges. Hence it makes the weak talent Combustion even worse since LB DoT crits are vastly smaller than FB/FFB crits.
