I just started playing this game a few days ago. I've found that Archer is a very hard class to play. I usually have at least a 1:1 kill ratio, generally better, with other classes. When I tried Archer once I went 2:15, and the 2 kills were with the sword
And usually I don't find them that much of a threat either. However, one of the last matches I played was very different. There were 5 archers on the other team all working together. Maybe connected by a LAN. They all ran in a very tight formation and all seemed to target the same enemy. That was a very tough nut to crack. You would charge them and have 5 arrows coming at you. One guy charging was sure to die. Same thing with two.
So I changed my initial view. At first I thought they were the weakest class. However, if a few of them work together to take down targets, they can be pretty good.
