A few co-op missions amongst a giant vault of solo content isn't hate, it's bending over backwards to try to accommodate everyone
If they truly hated solo players, matchmaking wouldn't exist, and everything would require atleast 2 players to launch
I myself am a solo player, and that's by choice, I have several raid Exotics, I just can't deal with the social anxiety and peer pressure
But we are a minority, most people who purchased Final Shape also completed Dual Destiny with no problem, you can't expect them to make everything centered around us , just unrealistic
