Failsafe actually could be a very cool Implant. Currently putting it into a slot is very similar to leaving the slot empty. 'Battle Hardened' - 50% reduced flinch, kills makes it double for 10 seconds. 'Assimilate' - head shot kill grants 200 shield and 10% ability. 'Survivalist' - Shield delay reduced by 1 second, Shield brake: Sprint speed, reload speed increased for 6 seconds (12 cd) 'Failsafe' - Shield brake: 20% Ability received (20 SEC COOLDOWN) and receiving melee damage during the cooldown will shock the attacker for 150 non-lethal damage....wow so useful! 'Nanomesh Specialist' does the exact same job as Failsafe but much better.
While i would love it to be better, there is a reason that cool down exists, because pairing it with assimilate gets memes
