You're really exaggerating how big these changes were. Nascent Flash feels a bit smoother when you just want to use it on yourself, but it's not like you couldn't already do that in group content (I'd hope your groups aren't dying often enough to leave no one alive to use it on). The extra Eye duration from Inner Release is just worth one extra Path every 3 minutes. You're not fitting a lot more Paths in and you're not getting a lot more gauge for Fell Cleave, you're just rearranging Path/Eye because it can stack up to 60s.
