I just activated maximum nanosuit (with full health) and I died immediatley when someone shot at me, just the same like you woul have normal armor mode on.
The previous was way better, then you really had advantage to score some kills after a 7 killstreak(just like Ceph gunship). If you have a killstreak of 7, I think you should be rewarded with full Maximum Nanosuit..
Will this change in the future?
