Tank drivers acting as gunners in PS2

[Malorn]

Any sort of one-time cost, unless it is massive (takes more than a few days), will have little to no impact on the prevalence of vehicles we see. It will affect what you see on Day 1, but after a week or two zero impact.

If a 1-man tank is an effective killing machine then we will see a lot of them. If it isn't an effective killing machine then they'll be buffed until they are, otherwise you won't see many tanks at all.
