tb can attack while running, just need +speed and stay close =.=, in ice form he has the -speed debuff, so hes always close, reg has range etc...
Wrong. Even if TB have 8.1 in run speed with both swift anklet and speedbots and fire aura, he still can´t shoot-on-the-move even against an un-upgraded Rook! TB just moves a few steps, stops, tries to get a shot of, but rook have moved out of range before tb has gotten his shot of, so he discontinues the shot, starts chasing again, stops ->repeat. He never gets a shot of chasing anything no matter how slow it is... in fire form...
Just try anyone else, regulus with or without wings have no trouble chase-attacking, neither does QoT or anyone else.
