Also one more thing as Neutral:
Add indicators to why team lost ticket like in bfV with flag representing ticket bleeding add skull represent death of player.
Not so neutral:
Critical mission failure is pointless, when you capturing all the objectives you hold them for 20 seconds 40 seconds at max. This is bad idea because team who let enemy capture all objectives and regain control of even one of them will not feel any consequences of they bad play. What will be good solution is add "Extreme ticket bleeding" like in bfV when if one team hold all of the objectives tickets starts to drain extremely fast and even if team lost control of all objectives the other team will suffer consequences of bad play by losing lot of tickets.
