Sounds like a great idea HT but you may not have to go that far. If the fuel factory is 75% then the
lowest amount of fuel available at the fields could also = 75% etc...
Or just add more fuel tanks, fuel mod at x1, make it easier to resupply fuel and reduce fuel rebuild times.

ADDED EDITORIAL ON SUICIDE
The game is where it's at because the "rules" make suicidal attacks a valid tactic. While these "rules" worked well in the beginning, and in past games, but the growth of the player base has changed the nature of the main. The emotional confrontation about strat vs. furballers divides the players between those who accept suicide tactics as part of the game, and those who reject it based on the unbalanced impact it has on them. I don’t think anyone on either side of the issue cares if a player wants to kill himself over and over. All that matters is having fun.
Despite all the rhetoric that may arise from suggesting the re-design of the strategic parameters of the game there is a way to restore balance. Not only in terms of game play but also with those in the community who are entrenched in one side or the other.
IMHO the smart thing to do would be to change the game's rules to eliminate the reason for the emotional confrontation and do away with the split in the player base. Again IMO moving the reset trigger away from the airfields to the factories and cities will do just that by shifting the direction of the "strat" players away from porking airfields but not eliminate it completely.
The key is not to please one group over the other, but to make both of them happy. The strat player will still have value in base capture to get closer to the enemies factories and cities and to create some space between the enemy and his. I won't go into details but there have been a number of good proposals in the past.
Some have advocated multiple arenas. Multiple arenas will only validate the split within the community. We all can imagine the banter on the board if this happens:
“
Those suicide gang bangers in the main vs. the suicide furballers in that other arena.”
My 2 cents......
