Which gems for my explosive arrow bow?

Until now I have been running what seems to be the standard league starter setup:
EA
Ballista Totem
Ignite Proliferation
Elemental Damage with Attacks
Combustion
Lifetap

Now I finally got an level 4 Empower and ignite proliferation on my gloves so I wanted to swap but just before re-coloring my bow I saw that a lot of EA builds use Awakened Burning Damage and Awakened Deadly Ailments. Should I aim for those or are Combustion and (Awakened) Elemental Damage with Attacks better?
