Mage's skill rsu

[pulupaker]

I was testing few days skill's rsu of different mage clases and have a lil question. As i know there must bu rsu like 1-2 seconds of attacking skills like hydro blast, prominence but on our server there is no rsu. I really tryed to make some movie but its insane situation. Some chars w/o sub have rsu and chars with sub havent it. Really hope that u won't give a fu,ck on that problem.
rsu=reuse
