It IS important in a game that has been patched countless times since that video was posted. If you can't figure out how the date is important, let me ask you this. What do you think would happen if I came to these forums complaining that mercenaries were overpowered, and then proceeded to post a video showing one kicking azz by spamming tracer missile over and over, dated Nov 2011?
It WAS possible to speed hack, to warp through walls, and skip all over the map; I've witnessed it, but I've been playing this game daily for quite a while now, and the only thing that I've seen in the past few months, across 3 different servers, that is even remotely suspicious, is some occasional convenient lag that no one can prove isn't just the game bugging out. I'm not saying it's impossible; there are some very talented people out there, but you're making it out to be that hacking is such a rampant problem, yet you can't capture it on video yourself, or post any RECENT evidence from anyone who has. Unfortunately for you, until you do provide some solid evidence, most people here are just going to think you're another bad, who may or may not have a talent for folding tinfoil hats.
Also, just because a search engine provides you with countless results from your search terms, doesn't mean that any of those results are up to date or relevant.
Oh, and lol
