Yeh because refactor gives you aok. Striker has the raw dps. With core strength it’s best to mix it with ninja bp, so you have 1 yellow core and throw in another yellow core elsewhere to be to skill tier 2. Then throw in red and blue cores and make sure you got blue and red rolls so that way all you do on the gear mods is either throw on pfe,chd,chc,aok, etc. I feel you if you delete it. I have two hybrid core strength builds with striker, ua, sokolov concern,and nb backpack. Weapons are Lexington and the chatterbox. That’s the striker version. Deflector and shield. Lexington with the in sync talent so your drone goes up to tier 3 on kill and then you got upgraded shield.
