If you want to Rocket yourself into an enemy WvW blob and you want to get out alive as well, you shouldn't do it in the first place.
This is literally the third most common reason I’m rocking the rocket boots: A.E.D->Rocket Boots [into blob]-> Slick Shoes(-> *when needed* Slick Shoes Toolbelt)->Mortar Kit 4->Rocket Boots [hopefully pointed somewhere without red circles]->Mortar Kit 1-4 behind me while running away. That can usually bait an enemy Zerg into chasing me for a bit while the tag gets to whatever they were thinking about hitting. So, rocket boots are great for trolling. Half a second… yeah, I’m with the ‘weird hill’ guy on that one. They seem great to me. What I’d so dig on would be if Tool Kit 5 didn’t take so long to cast and it worked in an arc like the necro pull. That would be even more troll-worthy. Or, if they were going to reduce any CD, let it be downstate 3; just lemme get the satisfaction of a good blast before I go.
edit: the first reason is breaking contact. Second, chasing down willbenders & rangers.
