Bard is only strong due to mobility, nothing else. When mobility is taken out of the equation, they're by far not the highest DPS, probably 3rd below Monk and Black Mage (imo, im not sure about smn/lnc that well)

In my opinion, a nerf is not needed, and some nerfs will completely kill the class
- Remove invigorate, class dead
- Remove Internal Release, DPS be probably lower than a pld lol be broken

Blood for Blood I can get by with being removed, its good but its not going to kill the class. Since its just like having another Raging Strikes.

I expect something along the lines of:
- Internal Release down to 10% when subclassed
- Straight Shot's additional affect only gives the 10% when the skill is on Crit Hit state (right now you can have constant 10% up)

These only two I can think of that could reduce the overall DPS, but not completely kill it. Your Crit would go down from ~45 to ~35 overall and the straight shot benefit would be more RNG.
