Who to upgrade?

Vader- Culling BLade lvl 8 (10+ bonus damage and can't be evaded is pretty sweet since a lot of times they just evade it)


Boba Fett - EE-3 Carabine lvl 8( 15% bonus daamge to basic attacks?sweet!)
- Death from above lvl 8 (Ability block,this can wait,I've got vader with his basic and his ability)

Phasma - Onslaught,basic ability lvl 8 ( again ,15% bonus damage is pretty sweet considering phasma doesn't deal as much dmg when she doesn't have advantage.)
- Victory March lvl 8 ( -1 cooldown,this can be pretty pretty damn usefull)
-Fusillade(this can wait,i've got vader with that already,althought 15% + speed down to 75% speed down is a guaranteed speed down on the enemy)

Main contestant? Darth Maul : Raging storm(lvl 8) *(bonus effect chance 100%,I don't find this THAT usefull)
Whirling blade (lvl 8) ( +15% dmg,pretty sweet considering it does already a ton of dmg)

And now for my favourite ability:

Maul's Power of hatred(lvl 8) >is a big boost to him,but i'm not sure i should take it since he's not always viable.
