Lol, well there are "hacks" edits more precisely. The zoom patch is the only thing possible right now. You can't bypass FoW since it is server sided, can't cheat gold since it is server sided. Can't hack game time to increase IP and XP earned.. There's a lot you can't do. However there are somethings such as "lag tricks" that can confuse their server and possibly give favorable outcomes. However replicating these is an extremely difficult matter. But with the lag trick you can confuse the server to thinking you are somewhere without actually being there, like ghosting only you have to convince the server to think that you are in two places at once and act accordingly to the ghost. But like I said it's very difficult to replicate the same occurance consistently in each game.
