I for one, Love playing WarZ. I have played it since the day it was released. I play with a group of people, mostly from the UK or what not.
The real problems....
1. Their real problem is that they let people into a Paid Alpha version of the game. The community that actually paid to play the game in alpha, has this mentality that they paid for a full game. They don't understand that what they bought into was alpha. If the game was a closed alpha, you wouldn't have the complains you do now. The community of this game has ruined the forums, you can't go there without people just complaining about everything. Instead of testing the game, and finding glitches, and reporting bugs. People complain about other people "hacking" and the lack of loot, and the in game micro-transactions.
2. Their PR sucks. Im not sure where they are actually, but whoever their mouth piece is, Sergey, he isn't very bright and only succeeds at furthering the disappointment. His Q&A's are always contradicting to his forum posts and he never answers a question completely. JohnnyTruant did a Ask Me Anything on Reddit, and only answered easy lame questions. They just need a decent PR person.
3. Hackers. While people have claimed to be killed by hackers, I have no encountered one. But, thats just me. I play on low population servers, and play with a group. If someone kills one of us, we kill that person.I haven't seen it but its for sure out there. They haven't done anything to stop them. The thing they did do was plant items in places you can only get to if you are hacking... those items had a hidden tag on them, then they banned anyone who had that tag. which sucked, because some people killed hackers, and got the loot, and then got banned wrongfully. Which they have been unbanned now, but its lame.
4. The in game micro-transactions. I for one, never spend real money on anything, once I get a game. It makes no sense to buy these things. In War Z, there are cosmetic items, like flares, chemlights, hats and such. And now, ammor for certain guns, and backpacks for storing loot. Nothing in the store is pay to win, nor is it worth me spending money on. They tried to make it cost money to have a clan. But with no real functionality in their clan features, its not worth it. We just all join a Axon Dolby server and play that way.
This game has potential to be a really good game. But you can't help to be skeptical about their intentions. There are good points to all sides of it. I like to be optimistic and hope that the game will continue to get better. Their track record isn't that great at the moment, and they still don't have alot of features that they claimed to have. They do have a timeline for certain things, but I doubt it will be on time. I wouldn't recommend buying it right now. I'd wait until they add the things that will make this a better game. Right now, if you don't have a team, you will run around, and get shot on sight. Which is no way to play the game.
