I thought it would be neat if when using the PvE build with Sunspots, "Siegebreaker," they added the Death From Above perk. If activated on ground, the Titan would slam the ground, immediately creating a sunspot, instead of doing the normal activation animation. If in air, he would do a Death From Above style charge towards the ground and create a Sunspot. The reason I propose this suggestion is because I find it annoying having to aim into the ground and throw a hammer manually before targeting enemies. Its a clunky feeling, but is definitely the correct way to do it in PvE. This could either be incorporated into a new subclass node, or an addition to Siegebreaker.
