I bought the WOW already... and i would like to start now.. but because of RO giving me nightmare (the ping increased to 1.4k at night )... i would like to get some advice here...

depends on ur broadband connection..if u're using 1MB broadband, the average ping is about 500 to 1k..

is that smooth?

Depends on which IP address segment you get, ping can range from 450-1300ms. Anything below <1000 is still playable

even at night time?

Roughly around 450~700ms

500 to malaysian standard is playable. 200-300 is excellent

but in US their ping all at 1-100ms >_<

1mb and 512 k connection doesn't make any difference at all...mine's been 500 average..nice and smooth

yea~ mine also same as above =)
malaysia broadband not as good as US >"<

broadband quality is just half of the issue.
The main thing is the distance between our coms and the servers in US.

I'm using 512KB, on a new server (Sen'Jin), but my ping is always above 800, why is that?

You just hit the nail right on the head there buddy...

BTW, has WoW been officially launched in M'sia?

nop.

i still manage to play with 700ms. i still get to kill a druid after he uses Natures Swiftness but never did heal coz i POM pyroblasted him. btw, his NS activated bout 3/4of a sec before my POM.

few week ago line like 200 -300 now got 600-1000.. mmm the line got hickup again.. hope will be better soon... ive heard this year Tmnet will upgrade all their facility.. so expecting beter connection HOPEFULLY la..

I am getting pings like about 200 - up to whopping 900 ms, but so far it's ok and quite stable, only once a while i get booted out of the game.

just sign up the game ... my ping was 300-600...

lucky you. nicer ping than me.

my average ping is around 500. But its very smooth

my latency bar always red color de -___-"

color doesn't matter, its always red for us. but it still is smooth, unlike when US players get red. according to them it lags and they can't play.
