Connection
The feel of boots in the ground, grassroots classic battlefield is great, the maps I saw were great with variety for long sniping windows to right corners for close quarters. The class system although almost ripped straight from some of the only good aspects of call of duty feel refreshed. To a degree battlefield is back to where it was around battlefield 4 for me which isn't a bad thing, although I would of liked to see a super large scale map and how that felt to play and to see if the servers could hold up to it, as this was 42s issue on launch.
Negatively there was some balancing issues with gunplay, shotgun range was massive and the LMG lacking any sort of recoil (although fun) just meant you could be beamed anywhere you went.
Getting dashboard mid match on week 2 because of connection crashes plagued me over the 2 days, for some reason bullet connection was also apparent on week 2, I believe this was because of crowded servers and hopefully could be fixed. Some points I would be in cover then just die or similar I would shoot someone, begin to reload and then it would register the kill ( no this isn't because someone else shot them this happend on multiple one on one occasion)
Overall state of the game as is still feels much more playable than any other shooter if it's type currently. Can't wait for official release.
