The map is also designed to make you explore and try to reach some places by climbing. There are hidden chests, places difficult to reach where you can build a cool base… flying trivializes that. I can build a base and get rid of doors, its main weakness, just making it an inescalable tower sitting on a high mesa. You can only access via its roof, plagued with thralls so you can’t just land on it unscathed. Anyone who can’t directly fly in can now only opt to try to use siege weapons from below, since there’s no way to climb to use bombs.
If someone does dare to attack me, I can find their base in minutes just by flying accross the map with a couple friends, and the rest just searching places that wouldn’t be noticed from the skies. There wouldn’t be a nerf uproar, there’d be people with pitchforks and torches asking for the dev team to kindly step out of Funcom’s offices to have a hearty chat.
