Tactical batter question - UI attack delay

Say if a character has enough action points to attack twice.  after the first attack, I had to wait for a few seconds to attack the second time, which is quite annoying in mid-game.  did I miss a game setup, or am I stuck with that delay?

Thanks for any answers

p.s.  The other annoying issue I wanted to complain about was fixed in yesterday's patch - where after every attack, the screen shakes once, which causes a headache.  High Five!
