Since the advent of the Frostbite engine in the Bad Company series, there has been a progressive effort by DICE to build upon their efforts by supplementing their subsequent games with advancements to their engine. DICE's additions to their recent Battlefield games have been nothing short of a disaster. Long gone is the unbelievable replay value that their games brought to the table. The thoughtful, intricate design that made playing on BF maps a joy is nonexistent today. The character development, physics and interactions with the environment are regularly bugged and inconsistent. The map design has been reduced to garbage, the flag layouts on Conquest are a joke, and the class balance as well as the weapon balance is awful. The game is plagued with outright broken animations and in-game interactions and reeks of something that was rushed or not tested enough. Not to mention the UI has problem after problem that one could discover after playing the game for mere minutes (as is the same for many of these other issues).
With the exception of the high gloss graphics (that ultimately deteriorate the gameplay due to the lack of visibility), Battlefield has taken a step back in just about every aspect in the last 5 years. No, this is not a dramatization of the current situation at hand. It is the honest truth from someone who knows these games inside and out. You can check my stats if you like to see how I perform in these games (psn: oSiGHTo). Myself and many others that I played with on a near daily basis are disgusted with how this franchise has turned out. Many of them gave up on the several prior titles, not wanting to deal with all of the problems and subpar gameplay.
You can look to only a few places for this categorical step back in Battlefield. I believe today, the mass exodus of DICE employees from the studio that is notorious for great games is the primary reason for this inconsistent and seemingly discontinued pensive development. I have been wholeheartedly confused since Battlefield 4 when I see game after game, a different direction is taken in terms of various design elements, such as the User Interface, unlock system, game modes or basic customization that omits certain key features.
My conclusion to this obvious predicament is a difficult one. Ideally, as an EA executive overseeing my stock price literally cut in half in only 6 months time, I would want to hire back all of the key personnel that moved on from the studio. Upon assessing the concerns, one would think a literal return to DICE's old ways would create an extremely receptive output. Of course in the world of business, such a thing is unlikely. Therefore, I would simply start over on this franchise and look to return to what was great in the previous, well-received games. Yes, this includes a more barebones Frostbite engine, and a close examination into the older BF titles pre-BF4 that were taken very seriously. Stop trying to build on what is afflicted with an endless supply of complaints. Your template is there, but it is being ignored or forgotten.
