Warlord, Lighting Spear, Unsuitable Terms!!!!!

[Dannyboy]

Hello all fellow Warlords, or X Warlords.

 

So I've been away from the game since C4, so this skill is new to me.  I absolutely love it of course as it makes us a bit more viable.  Yet 90% of the time I keep seeing this bullshit message everytime I try to use it.  If I'm holding down Ctrl or not it does not matter I see the same thing.  It works like 10% of the time, I can't seem to figure out what and why it works sometimes and not others.

 

"Lighting Spear, cannot be used due to unsuitable terms."     

 

Please help me understand wtf is going on,  Beyond frustrating.

 

Thanks,
