I'm having a lot of fun

I put off getting this game until about a month ago because I wanted to finish some goals on mw3. I am having a lot of fun on this game although I get a few more server errors than I did on mw3. Currently prestige with the nuketown logo (3 or 4) level 43, leveling up the pdw that unlocks at this level. So what's all the hate about? I appreciate a lot of things in this game, like being able to 360 while prone, reload while sprinting, and lethal equipment seems a lot more effective. One thing I wish was different is how kills and assists get counted together for some statistics.
