Some thoughts on what I've seen.
The game looks really good. Without playing yet, things look to be in good shape, decently balanced, (except slug shotgun), and overall a good start.
Guns have there strengths. Yes, some are better than others, but its the nature of things, (some extremes however).
Maps look good and offer variety of play styles.
Spotting while downed is something I think should be removed. A downed player is out of comission, they shouldn't be able to support the players around them in that state. I do understand parties can call out, but its better that way than to have their position marked.
I'm excited to try the beta and get a better look/feel into these thoughts.
This was a reply elsewhere, but fits:
Snipers are a long range weapon, not cqb. The sweet spot encourages this. They are a heavy percision rifle. Smgs and shotguns should dominate in close quarters, assault in mid. To make them work everywhere defeats the purpose of the selection. Recon has other tools to play up close.
The ttk being fast also makes you think before going in and encourages squad play. Strength in numbers, if you charge and act without thinking, you get wiped costing your team.
