Nobody can properly prepare for that ult.
Not just the first time... :|
It is so disorienting when you get Kal ult cause you need to register what just happened to you and why your screen is green. After having it happen to me, I understand why they don't immediately fire after pulling during an engage
First time it happened it scared me because I had NO IDEA WHAT WAS HAPPENING!
omg is that guy ok??
unfortunately I get massive lag spikes when I get Kalista ulted so...
I didn't know that when you launch and hit an enemy you reappear. I learned this after Kalista tried to save me from a 4 man gank. ._.
