Tbh, some SEA players are cocky. No offence, but some of them really are.

guy, i just want to check, is it normal when i click "store", there is a pop out come, security alert, want me to press yes and no for the certificate issuer?

Well when you get to higher levels, the people are generally better. I rarely encounter people who complain about stuff like Ks and CS farming. Of course the you cant avoid the occasional trolls but flying spaghetti monster servers are ok and there is no lag. Believe it or not, of all the past 14 moths I've been playing, I've only encountered 1 troll and it was the enemy team. The only complain I have is that it's lacking some of the features like what the NA servers have such as the refund feature.
