Well this is only a day after release but...
1. I like Dark Zone PvP concept. Really adds in a lot of strategies and planning considering if you die with all your loot, it's all gone, which keeps people alert and kinda reminds me of the Wilderness in RuneScape. I don't like the unstable servers, my cousin can't even start the game and play (whether it's him or the servers I'm not sure)

then again it is Ubisoft...
2.I hope in the future, they provide more character customization. I feel as though the character that I made at the beginning of the game doesn't really match me well and there weren't really many faces, hairstyles, and other things of that nature to choose from.
