I've seen a major uptick in lag spikes recently. I game with my brother sitting next to me. We have identical computers and are using the same internet connection, I suddenly have bad lag and he does not. Magically the node I was guarding is turned.
I am 100% certain there are hacks being used. I PUG'ed a Huttball game that our side was scoring goals just as soon as we could get the ball. I thought "Oh I dropped in with a premade that knows how to play Huttball". Then one of my team mates said in general that he is not associated with player X and that Player X is running a seed hack. After the match, Player X talked about running the speed hack to his friends in General chat.
