skills not working properly, specialy today

[Decrpito]

hi everyone, im having troubles casting my skills, specially frost bolt, and its not a lag issue cause i have a very good ping, its very anoying, u charge the skill, release, and nothing happens, id did not take mana but neither release. Plz let me know ur comments.

forget it, its lag, even my ping is green almost all the time, sometimes go yellow and red, and that causes the issue, today the game has been very laggy, im on a strong wifi connection playing in a pc ;/
