Friday and Saturday night I totally "cheong" DOTA throughtout the night.Sleep at 5.30am before my moms wake up for work.I using a new hero - Zeus. Also is a lightning siao,much more powerful then Razor in pawning other hero.But I still miss my "cheong" tower with Razor.
Wonder when can I play DOTA with my brother those friends with my next hero ---> Zeus.
