I really hate the Loner playstyle because it incentivizes behavior counter to game design and mechanics, plus it really fucks over your team by denying them your toughness regen while rushing ahead triggers more spawns on them.
Instead, try to orbit your team outside of coherency radius, or try to stay just ahead of them. If your crew uses a buddy system, communicate that you need to be their electron to their tritium so they aren't screwing over your buffs.
