I'm hesitant to respond here, I don't really want to take away from Tar's point, but I have to say that its nuts to require me to read through comments to get the news anouncements. I may scroll through the comments occasionally, but I shouldn't be required to in order to get important information about the game.
To be honest, this was a great missed opportunity for you on the PR side. A whole new post on all the social media should have been made: "We've heard your feedback and have made a change (because you asked for it)!!!" Instead you've hidden it inside comment sections that people have to go out of their way to look through. Big miss.
Also, I do agree with Tar that objectives can be challenging, but they shouldn't be super hard either. You are doing this to give away a free pilot as long as you play A LOT of the game. If your objective is to encourage people to play the game, then just keep making the endurance oriented objectives. Requireing players to kill 50 mechs, cool. Requireing players to spend A-Coins to upgrade items they weren't going to upgrade otherwise, NOT cool. Keep in mind your target audience!! With a free pilot, its not the big spenders or end game players but the early and mid game players. Skill levels are low and A-Coins are also low.
