First of all the spawns are the same as they have been in previous COD games
Maybe you mean spawns are the same as they have been in previous IW games? I can't comment on those, but i know without doubt that this spawn system is nothing like Black Ops 2. It had its own issues, mostly caused by the small maps, but never in a gameplay time that spanned ~60,000 kills did I spawn not knowing which way to run. In Ghosts it's a 50/50 split as far as guessing which side of you the enemy is on.
All that said I think in general Ghosts is a very good game. Connectivity and "lag comp" -- however you want to define that -- seem to be pretty reliable and consistent. I ***** and moan as much as anybody, but overall I feel like I have far fewer "wtf" deaths than I did in BO2.
