yes - dont think a GUI convert will earn you respect. infact, it will lose you it.
anyways,
-you leak a ton of groups
-you leak 3 locations: 1 per unit create
-the spell itself is 2 or 3 chain lightnings, plus eyecandy
-boy, does it lag ( tested it on a slow computer: this comp helps me evaluate whether the spells leak badly or not. they ESPECIALLY should not lag ( like this one did ) because someone placed about 500 units on the test map... w/e )
Well this spell is "okay" but can be done much easier and you definitly Converted the the Jass thing from GUI because you used global variables and the GUI "for" stuff.
