'Guardians can leap, Vanguards can charge, but Shadows are screwed because Force Speed is not a proper gap-closer. It's not just a click'n'hit ability.'
I agree, you don't just target the enemy and tadaaa, there you are. Leaping or storming to your enemy truly can be effective, especially during fights like Firebrand & Stormcaller in the Explosive Conflict. However, if you learn to rotate your camera, strafe and jump, Force Speed is a far more flexible ability than Force Leap or Storm. There is a common knowledge that you need to learn to handle a Shadow in order to be an efficient tank – this applies here. You sometimes have to jump, change direction, but you don't need to target anything to be able to rush anywhere! Force Speed is not limited by your sorroundings and you can still use abilities while speeding. How comfortable it is to have Force Speed during Kephess encounter in Terror from Beyond when you need to cleanse yourself of the electric debuff. Additionally, Force Leap/Storm cannot be used on targets in cover, not to mention that it sometimes even messes up the bosses cast which might give those in charge of interrupting a hard time (the cast occurs again in 3 seconds if interrupted by such an ability). Yet, Force Leap or Storm can save you from falling in various occasions (SoA etc.) and offer a direct path toward your target even through AoE without practically 'stepping into that AoE'. And, of course, PvP is a totally different matter.
To summarize, I'm not trying to prove Force Speed to be better than Force Leap or Storm, I just wanted to point out that it definitely can be treated as a proper gap-closing ability even though it technically isn't. Feel free to question my statement, I'm always happy to discuss any mechanic.
A post focusing on survivability and cooldowns coming soon, until then...
