Been enjoying this build on herioc and completed serval retaliations solo on heroic with it .. the problem with retailation especially on heroic that literally the whole map is hunting you along with the kill squads.. i tried the full red striker didn't stand a chance despite the good damage.. so i was looking for something that gives me more bonus armour..self healing (armour regen).. with a good armour on kill without sacrifice much damage and also to fits my playstyle .. with the ninja bike ..i have 178+k armor on kill and 22+k armor regen .. because of the mask which is pretty significant especially in retailation with a good rate of fire and the bouns AR damage with salvio and with the flatline and HB stacks iam doing amount of good damage.. the down side is that my CHD at 80+ but i would say it's not that bad and didn't bother me that much since i went for more survivability and the damage is good.. any way still experimenting with the HB gear set .. it's like my fourth month in the division 2 and i love it so far .. looking forward for the feedback if iam doing ok since Iam kinda new to the game.. and what can be improved..
