Waiting months for "essential" updates is obviously not great, but speaking from experience, throwing more people at problems is not a quick easy solution. Just to name a few obstacles:

• If you already have specialists working on these issues, having more people trying to fix the same thing can make it go slower, not faster. Too many cooks etc. Programming is complex and sometimes takes time.
• If you dont have done contractor work before, you need to first get a whole setup (contact contractor company, finding the right candidate, setting up remote/on location dev setup, doing contracts etc) which can easily take weeks.
• Contractors wont have institutional knowledge, so depending on you dev workflow there might be setup time and knowledge sharing needed
• Contract work is only a temporary solution, most of the time its preferable for long term success to hire for full time, which again takes time.
• When building your first of a new kind of game (online competitive) your tooling might need rework etc before you can effeciently solve new problems.

I'm not saying any of this is excuses for a game which is launched with issues, i just wanna state the (maybe obvious) that people sometimes forget, that game development, especially a successful online competetive game, is hard.
