Spamming SP was better? Lawl.
KE is more diverse now, but still too OP.
No, it bloody isn't. Can I go Spirit Blade, Fade Cloak, Fade Step, Barrier, Dispel, Mind Blast, Resurgence/Revival, Mark Of The Rift? No, I can't, because you have to go DAMAGE DAMAGE DAMAGE in order to do damage with Spirit Blade. Where once upon a time you could build your Knight Enchanter to be situational while depending on Spirit Blade for your damage, you are now obligated to go for a DPS build.
Once again Bioware shows its desire to move away from tactical combat and into pure action combat. The Knight-Enchanter has not diversified, it now forces you into a particular build to be effective, and that is sad for anyone who actually likes to try something different.
And in hindsight, Spirit Blade's damage was not that overpowered, because it attacks a whole buttload slower than normal attack. It's its synergies with everything else that made it so powerful, and those synergies are still there.
