First off, I thoroughly enjoy the fact the extremely angry runway bug from the 0.4 era was fixed. This allowed the implementation of the midair rearm being disabled.
However the landing bug, as evidenced by most pilots, is still there, and still results in the total loss of asset and/or death of the player.
For this reason I think most servers should enable the midair rearm until this bug is fixed. The turnaround time of landing to rearm vs midair is not very substantial, so the gameplay impact should be marginal, if not non-existent entirely.
As it stands right now with most servers having this setting on default (disabled), it practically dooms ASF pilots to either lose their asset with no money to buy another, or end up suiciding.
Take this as an example:
Mechs power down to repair, like all assets. Now imagine a random bug that would explode your mech at random every few times you shut down to repair. If there was an option to override that function, and allow mechs to repair powered up, I'm sure most servers would choose to override it. Unfortunately I think the dedicated ASF community is quite small, so our voices are generally not heard.
