As has been pointed out, you don't really need to play any more than the alpha/beta to know what the gameplay will be like for the final version... Different game modes and different maps is not going to change the basics/core of the gameplay...
Tbh, the "hate" is justified imo, for many this was going to be the next big MP game to last us until the next BF game but instead they give us this, a game that will be lucky to last more than a few months.
Also, most people who have/are playing the game now have admitted to the gameplay being shallow, no depth etc. regardless of it being fun and as some have already said, if you take away the amazing graphics and star wars theme, chances are, those people would never have even bothered with the open beta. At the end of the day, if it weren't for the upcoming film and all the star wars hype, this game would never been announced/released, it is a quick cash grab for EA, nothing else.
As for the lack of "hate" posts and posts in general, give it a few days as most people won't be unlocking it early like the few who have done on here but I have to say, regardless of that, there really doesn't seem to be much interest in the game on here, previous MP launches like BF 4/3 seemed to be a lot more popular....
Hardline was very similar to BF 4 and was "hated" for different reasons:
- it should have been a DLC, the core of the game was the same except no/little vehicles, a cop/robbers theme with a few tweaks here and there.... Star wars is far closer to COD/titan fall than it is to hardline/BF
- developers put on the good act of listening and doing what the majority wanted for the alpha/beta but come the final release, they didn't do a single thing until it was too late and afaik, still haven't changed what many have been begging for since release i.e. the insta TTK, netcode, awful weapon balance, commander mode being OP
Had they listened and done what most wanted, I put money on it that the game would have been alive for a lot longer.
EDIT:
Even lvlcap who is a ronku whore said the game lacks depth and without it being star war, it would be dead in months
EDIT 2:
Even on xfactor's stream, he said 20v20 walker assault will get boring quickly and that is the best game mode according to him....
Again, if people enjoy it, fair enough and glad you guys are having a good time but I don't think anyone can deny that the game had so much more potential.
