100 blocks off the ground extremely reduces zeppelin capabilities, like when trading traversing mountain ranges, and like in wars, where they're slow to move and turn, they get hit easily, I think making their height limit higher little than 100 should balance out, since I understand it's too OP if it's too high up, but there are some concerns about them being too low to the point they get obstructed with structures or cannot even park in towers due to either you can't go high enough or there's obstruction due to you can't go high past the said structure, they've become choking to use, I greatly example the traversing the Himalayan ranges
