Adding a 2 - 5 minute delay is the same as just disabling them realistically.
I think pures want to be able to return to fights, just not as fast.
Skill wise just disabling the loadouts seems like it'd be a better idea than a delay since this means the team who's members are more competent at re-gearing get the advantage.
what would stop pures from returning? kinda confused by what you said, like i really only use the load out to gear for certain slayer tasks etc and pures will still be able to return with the delay
