I don’t know about anyone else, but I always liked it when you couldn’t use fuel under water or to climb steep cliffs. If you have fuel, use it, don’t wait until you’re in a bad situation.
I am coming from a viewpoint that fuel is not a bail out item, but a strategic one. I think fuel, like in the past, should be used based on your current positioning, and your assessment of your opponents next move. In past versions there would be times I would find fuel very important, or not use it at all depending on the situation. As it is now, it is kept in reserve just in case. Or more annoyingly, used to move little by little to avoid being hit 10 times straight.
