Regarding Lord Arkos is there a consensus on the faithless legion trait? FAQs don't really address it in a straightforward way.
What I'm really looking for is if there is a way to take arkos in a faithless detachment that uses alpha legion strats/relics/wl traits and units in that detachment can still benefit from arkos +1 to advance and charge ability.
My intent would be to use lord arkos to enable DS assaults by deep striking arkos with renascent infiltration. This would allow units with mok- icon to reliably charge.. such as terminators, chosen, etc.
However it seems that the rules interactions end up with a 'faithless' detachment being renegade chapters with dark raiders (no alpha legion specific stuff) or else something bizarre like red corsairs or another of the renegade chapters counts as (again no alpha legion stuff if you want the +1 ability).
