Instead of Garena, may I sugest heading over to www.dotapod.com.
It's formerly known as Zion (if anyone's interested) and the
servers are much faster than Garena's, due to lower amount of
gamers I suppose, but there are plenty of games to keep you busy
nevertheless. Plus if you're registered and trawl the community
forums there, you'll find a healthy community that's growing, and
growing..
Check out Dotapod's forum here. (This link is an
affiliate link where I get 10 in-game gold if you visit it. Btw
these gold can't be converted into real cash or anything, it's just
the RPG style of the forums where you can use these gold. It's okay
if you want to visit a normal link like these http://Dotapod.com/Forum.)
I really enjoy Dotapod, or DP. I'm sure you will too.
