Mostly because many of us who have been around through Alpha and early access are bored, because EC lacks substance, because it only has a few maps and they are all running king of the hill. At this point anything that might improve long term playability is a gift from our lord on terra. Though I do sincerely doubt Campaigns will bring much to the game, because they don't involve new maps and game modes as far as i'm aware. Those are what EC really needs, along with more balancing and some incentive for people to play the less populated factions.
Now if they had planned for campaigns properly they would have launched them in a big patch with several more maps. That would be nice
Imo EC needs at least twice the number of maps we currently have. Minimum. But what could really turn EC into a milestone would be making maps much bigger.
This would help a lot, true. But bigger maps will require higher player numbers per match so I am not expecting it soon. But this is not enough for me. I think game require different mission objectives. I am extremly tired of running like an idiot from south to north to get objectives. This is making EC matches very repetitive and quickly boring. We need at least some aditional mission objectives. And I am not telling about boring "kill 5 enemies in xxx time". What i mean is get the supply drop, sabotage enemy vehicle spawn or ammunition supplies point etc.
