...Thanks to the free MP demo on Xbox One and let me just say this:

Connection matters.

This may seem obvious (for ANY pvp game), obviously, but it really does matter. Back in November, I had a much "cheaper" ISP with unknown speeds. But now, I have an Xfinity plan, which maxes at 50 mbps (Pinging around 44, that's what Titanfall tells me. It fluctuates more or less ), and Ghosts is easy as **** bro. Was hitting 25+ kills a game. But of course, I was playing against "low levels" on three maps who I assume have not played the game, and I myself already "knew" the maps in the demo. Mechanically, I don't see anything wrong with it based on what I've played. Everything I hated about it was based on my connection not giving me any chances. I may or may not return to completely though.

But, I'm sure even pro players with a connection better than mine find flaws.

 

Hope you get out of it, too! Haha, cause I know what playing on a shitty connection feels like.

Once you obtain a high quality ISP, all of what you described will turn out a win in your favor.
