You could always macro in the /recast "Blood for Blood" after an ability you use more often.

This will give you the time left in the chat box.

Ex:

/micon "Straight Shot"
/ac "Straight Shot"
/wait
/recast "Blood for Blood"

Personally I like having a /wait in there so when I spam the buttom it doesn't fill my chat with recast timers with the only downside being if you hit the next action before the gcd it won't display the recast at all.

But having the timers on the spells themselves would be preferred above all else.
