With that option you can roughly (very roughly, just an example, not very detailed) play 6 days a month without fleetsaving (in truth it could be even one or two more days I think):
Day 1, then day 2 and 3 in v-mode
Day 4, then day 5 to 7 in v-mode
Day 8, then day 9 to 12 in v-mode
Day 13, then day 14 to 18 in v-mode
Day 19, then day 20 to 24 in v-mode
Day 25, then day 26 to 30 in v-mode
It's not that bad, and people will be less likely to abuse v-mode. I don't like the fact that at some point you might be able to get back to playing after putting v-mode for some personal reason (not to abuse it), and you won't be able to come back until a few days later when it's enabled. In that regard, I see the 5 (or 6) times per month more reasonable; complete freedom to exit v-mode to those well intended, and just 5 days of playing at much for those who abuse v-mode.
