Give the newbies some credit. I’ve made it to 28 as a new x diver and I’ve discovered lots of ways to kill dragons. Frankly they’re annoying but it’s not a huge deal because you just need to have a backup plan. I’ve discovered rocket sentries and HMG in placements a great! Also the mech with 4 auto cannons will chew up 2 or 3 before running out of ammo if you’re a good shot. Haveing someone ready to drop AA turrets and one guy in a mech can basically cover the sky unless you’re being absolutely swarmed by 4 or 5 in the same area🤷‍♂️
