They're doing this for us, they're making sure we get the best game possible and some people really need to understand that.
No.
First off, what they are doing is potentially bad for us, them, and everyone involved. Because they launched the game with minimal features and haven't updated it substantially for months, it is quickly being forgotten and left behind. People are getting tired of it. I mean, the amount of content included at launch was staggeringly low. Player fatigue sets in. When it does launch. new potentially purchasers remember hearing the lukewarm comments about the early version, while people who own may already be tired of it. Keep in mind, unless they are developing a lot of things in parallel, we aren't getting full release for another year. That's from now, not the EA launch.
Secondly, this is by and large been a really poorly handled EA imo. TWI wanted to show "EA done right" but it has been the opposite imo. I can be down to help work the kinks out of a game. Or fine tune it even. But... we aren't involved in that process really. Look at Berserker's changes, that's being play tested to perfection internally before release. We aren't helping shape the game really, except in the loosest "work on this thing, it sucks" "okay cool, we will have something for that in 3 months and you can give us more feedback". The back and forth is shockingly low. The community can't really give much feedback with such a low amount of content.
It fact, their perfectionism really indicates, to me, they should never have done an EA game. An EA, like a beta, means you'll accept things that aren't finished. That means both the game and the individual aspects of it. The model for a gun doesn't have to be perfect, the animation can be wonky and unfinished in parts, you could even be using placeholders for sounds in a lot of places and it'd be understandable. If the community is there to help perfect the game.... we don't need to be given perfect content. If we are helping playtest, then maps can have bugs in the before shipping.
Maybe they have perfectly good reasons to be devoting time to recording new speech lines and modeling new characters rather than finalizing more important content like models/sounds/animations for guns, to get actual game changing content. Maybe they have some sort of parallel development, which is why we are stuck waiting for a rebalanced perk and two new ones in an update, rather than having that content spread out. The thing is, that would be useful information to communicate, not pointless development charts that are quite literally a graphical version of "no, we are working on stuff, trust us!"
This is, by far, one of the worst EA I've been a part of. I simply don't see any reason for it to be EA. They aren't gathering feedback in any useful amount, the game isn't finished enough for me to actually be glad to own it in it's current state, it will hurt the game long term due to driving off potential players, they spend time on things that absolutely do not need to be a priority right now(Anton comes to mind).
TL;DR What they are doing is not helping quality, or player satisfaction, or ensuring longevity, or indeed doing anything good for anyone involved. Also, the next time someone suggests adding a new character rather than working on perks/weapons/enemies for this content starved game, shoot them.
