Removing fuel will allow everyone to see the bomber reload timer, which will also encourage more hoverbombing! Let me see the bomber reload timer just so I don't have that situation where I try to drop a bomb just before 5 seconds elapsed since my last drop. It makes me feel dumb.
In all seriousness, fuel actually plays an influential role on how inties especially are used. If you've played Crossfire Canal ever, you've gotten into games where you have 100+ inties. The way fuel works now, you actually have to be cognizant of how you use your inties—selecting small groups to deal with small numbers of bombers or transports, and parking the majority of them in a place to conserve fuel. You certainly can't just select all inties and move everywhere all the time. If fuel were removed, you could just patrol massive groups of inties everywhere and it would completely the way game is played. I say we should keep fuel as a mechanic.
