Like many other people I've been mulling over the differences between these two classes, as they seem similar in many regards. One thing has become a real worry for me, something I cannot verify myself; that is in regards to the Spellslinger's innate power. So the Spellslinger's innate is basically a toggle buff, on an independent resource system. There has been a lot of discussion about the DPS of a Spellslinger Vs an Esper's DSP. Carbine has come out and said a few times that the Spellslinger is just barely behind the Esper; a trade off for most skills being mobile. My worry is that the Spellslinger DPS is balanced around using their innate to increase DPS. I looked at the innates more as a "bonus", "get out of jail", "oh sh*t button". Queue the Esper's innate, an invulnerability innate with no downside other than cooldown. If the Spellslinger's innate is nothing more than something you're required to use in your rotations to be "optimal" either for healing or DPS, that doesn't qualify as an innate. In that case the Spellslinger's innate is basically equal to an Esper's psi-points. tldr If Spellslinger innate is factored into skill damage balancing, then it is not a bonus it's a requirement making it equal to Esper psi-points. Esper's innate is a pure bonus.
