Explosives Expert
Gained +40% to Critical Strike Multiplier against Burning Enemies. Up from +30%.
Lost 30% Increased Area of Effect and 8% Area Damage taken from Hits.
Losing AoE hurts. The additional 1% per mine from bomb specialist doesn't make up the loss so you'll probably want to grab the helm enchant (24% BL AoE) or allocate/anoint Blast Waves.

Born in the Shadows
Lost 30% increased damage against blinded enemies.
Enemies are now blinded on hit. Up from 25%.
Lost some damage for some defense.

Pyromaniac
Lost mana reservation on mine skills. Was 20% reduced mana reservation.
Only need 5 mines detonated recently (down from 10) to reach 10% life per second regen.
Anomalous Trap & Mine Damage Support helps here if you weren't already using it before.

Demo Specialist
Gained 150% increased Effect of Auras from mines. Up from 100%.
Scales notables like Volatile Mines & Destructive Apparatus, requiring fewer mines to reach caps. Should also affect High-Impact Mine Support.
"
Bomb Specialist
Gain 5% Increased Area of Effect for each Mine. Up from 4%.
25% Increased Mine throwing speed if mine detonated recently. Up from 20%.
Mines have 25% increased detonation speed. Up from 20%.
Lost 40% Increased Damage if mines detonated recently.
We're really just making up for area lost in Explosives Expert. The throwing and detonation speeds are not going to be noticeable.
Summary
Build should be fine. You lose a little bit of damage from the ascendancy you can make up through harvest crafting. You won't have the mana pool to frontload maximum mines for bosses and will need more mana reservation or mana (%int from maven's orb?) to squeeze in more mines. We'll need to make sacrifices to get the area of effect back to where it was.
