Spent a good 5 hours today fighting mostly players from Brazil and was having those same issues. A lot of no hit reg on them where they where getting impossible shots on us (got 2 shotted by a JG from 30m/ish away while the guy was running away, as an example) Had 2 VIP missions where the VIP was basicly immune too everything except self damage, its just a bit frustrating is all. I do understand the bad ping though, when I first started playing I couldnt get above bronze because my ping was constantly in the 250ms-350ms range and it suuucked, the moment I got proper internet jumped up to gold in like 3-4 missions XD.
On this note i'm excited to see all the new/old players, but I do hope you'll get your own free servers soon. More so you can enjoy the game at playable ping than so i can quit bitchin about your ping causing issues with hitreg. (although I'll always fuzzy bunny about lag causing hitreg issues soooo :P)
