I soloed almost all of the quest but not the strike because that has matchmaking.

Yep, Zhalo helps big time for the first part with all the knights with arc shields. The 1st boss is easy and goes down with a few rockets. The next quest I found it helpful to just run past all the ads to the boss room. The taken wizards have void shields so you'll need a void secondary and just try to have enough time left on the clock so you can do the last part patiently. If you try to rush it the 3 wizards will kill you quickly in crossfire.

Of course
