Thoughts on MW3 -
Horrendous.
The maps are a giant sh*tstain and are a complete pain to do anything other than run around w/ a goddamn ACR 6.8 or UMP and spray your way into oblivion. They are bland, lacking in any semblance of variety, and cater to one play style only - running around w/ Marathon, Quickdraw, and Steady Aim or Stalker and trying to be Rambo.
The spawn system makes these ^ failures 10000x worse. I cannot believe how bad the f*cking spawns are. One time I running into a room near the middle on...Dome IIRC...w/ my Mk14 and killed a guy in the middle...only to have one spawn in the walkway behind me and another literally right where I just dropped the guy. Utter folly.
The shotguns are actually worse than they are in Black Ops (I seriously did not think this was possible in any way, shape, or form, but with the KSG12 it took me 4 shots on a 4-bar to kill a guy maybe 10m away!) it is exceedingly difficult to snipe w/ any degree of competency on these maps, and LMGs now make you move slower than Steven Hawking in marshmallow fluff, drop off badly at range, and have brutal idle sway.
All the assault rifles and SMGs are amazingly powerful, except for the simply horrendous M16A4 which borders on unusable, and all of them except the CM901 and PM-9 (just a reskinned Mini-Uzi so it was gonna be garbage) have very little recoil and stupendous range.
I would recommend a vasectomy over trying to reason w/ this pile of white dog sh*t.
RIP Infinity Ward. You certainly were not responsible for this catastrophe. West and Zampella, welcome in Respawn Entertainment, and take out the trash once and for all.
