Bf4 would need to fix the issues that bf3 has for me to consider buying it. No doubt it will be a 60e title too plus the dlc they will drip feed over the next year. Also I do not fancy paying 60+ quid for a game that will be replaced in a year or twos time.
As for the bugs/issues there are many imo that need to be fixed for bf4.
Firstly sun glare. It is stupid beyond belief to have a feature that basically blinds you in a game that you need to see the enemy. The blue tint makes the game look dull and boring. There is a thing called something like FXAA injector that basically makes the game look so much better. Once you try that the vanilla version of bf3 looks awful.
Next up is the lag compensation/net code. The net code in bf3 means you will often die when you go around corners. This happens in other games too but not to the extent that it does in bf3.
The bullet damage needs to be adjusted. I think it is a little stupid to headshot someone with a low powered rifle at very close range twice and they still have over 10% health.
The gun balancing needs to be adjusted. Imo slugs for shotguns should be removed as they make them way overpowered. Being able to kill someone at range with a shotgun in one hit to the leg is stupid especially when you use something like a scar L and two headshots wont kill.
The feel of the guns needs to be adjusted to imo. The game feels too spammy and you get so much spray and pray. Especially since the game rewards you for missing ie suppression. There really isnt a need to go for headshots in bf3 with a smg or assault rifle as it is quicker to aim for the body and just hit them 3/4 times. The only guns imo that feel any bit rewarding to use are the bolt snipers. Even the auto snipers just feel like spam. The pistols react the same too. Visually they seem to have recoil but they really dont. Just tap the mouse as fast as you can in the general direction of the other player they will go down.
Speaking of suppression, I for one think it is just another stupid way to help people get kills. I mean it promotes spraying rather than aiming. It also is very random. When sniping I have had times where I am almost blind due to suppression and I can headshot someone easily and it wont be a luck shot. Then there is times where A guy shoots one bullet and my aim goes all over the place.
The animations are a little spazzy too. If you watch someone bunny hopping across the map trying not to get shot it looks hilarious. It looks like they are skipping across the map. The other animations are the turning while running animations as the guys head goes all over the place because his body leans with the turning. Then you have the headshot animation. Shoot someone in the head and watch as they only have one hand on their gun and point to the air but still hit you. Then you have the looking at the ground animation but still headshoting you. Not to mention the one knife kills from half a mile away and also the immunity when knifing. I have put so many rounds into people when they are knifing someone only to see them turn around afterwards and one shot me with a shotgun and still have full health.
To me bf3 is a casual shooter. It just feels too imprecise and very spammy. The animations do not corelate to the actual opponents view and the net code will make you rage more often then not.
For me when I play bf3 I turn on music and play with no sound and just run around. I cannot take bf3 any bit seriously, it is just a game to chillout too. I find it hilarious watching people play so hard as if it is a competitive match sitting on a med pack behind cover spraying an m16 and when you just run around killing them they shout out at you calling hacks
In some ways bf3 was a nice step forward from bf2 but in other ways it just became crap. Imo it took a leaf outta cods book to try and appeal it to the masses and it worked but in doing so they make a shooter for the average joe rather than a shooter for the competitive scene.
The same can be said about the new counter strike with the addition of the stupid crap like fog of war and bland colours in the maps. Then you have the molotov and decoy grenades and nerfing of some good weapons. The things is at least the new cs is not a 50e game but rather a less than 15e game.
