This is sort of a general complaint with no real solution provided so sorry in advance but I continue to remain impressed at how utterly fucking atrocious PGI is at writing. The fact that their writing is the bottom of the barrel in a franchise with over a hundred shitty novels is just baffling, especially considering that they don't have to do fuck all themselves. They didn't need to make the setting of Battletech, they didn't need to make the map map, they didn't need to write the history of the setting, they didn't have to make up any factions or faction leaders or notable side characters or current events, etc. It's all just there waiting for Generic McProtagonist to observe and interact with in a noncommittal way thanks to the thousands and thousands of pages of writing and world-class wiki that already existed before MW5 was even a glint in their eye. Nobody was expecting anything better than "barely tolerable" from them but when one of the most frequent criticisms of the game is "this game would be better if the main plot didn't exist" with a postscript of "also for the love of christ please just let me mute the characters and skip dialogue" then you have a pretty remarkable fucky wucky on your hands.
As for the solution, I have no idea besides the extremely vague and unhelpful suggestion that they hire actual writers instead of whatever the fuck they're currently doing.
