Well, it is slower than a pre-aligned warp.
Indeed you could.
Taking more time is a disadvantage even if the enemy doesn’t know where you warped to, which would be an advantage. If you’re trying to run, the enemy could probably make a good educated guess as to where you could be warping to. Also, CCP could also add non-cloaked warp paths to d-scan or some other part of the scanning system.
Maybe someday we’ll be able to effect each other in warp, but it would probably require slower warp speeds.
And I’ll re-iterate that I have seen enough of the game to understand the skill’s usefulness during certain circumstances. I didn’t say the skill was useless or irrelevant, just not as relevant as it could be.
Kind of a moot point considering someone could warp to a different celestial and warp to the target destination at an angle that would avoid the bubble entirely. If you want to prevent people from getting to a certain place you need to bubble it in it’s entirety. A curved warp won’t help someone get to a destination that is thoroughly bubbled like it should be.
Curved warping is not a way to avoid bubbles or avoid capture. It’s just a different or perhaps more convenient way to warp.
