Fifth hanger slot, to buy or not to buy

Not really clear to me how does MM work, if it works at all. But imo it will do something like this for your particular case, how often do you mech out with 4 bots? If it's often, then you're probably gonna do more damage, caps and kills with 5 bots. Which means, you'll get up the leagues, which means MM will go nuts on you more often.
I don't think number of bots in your hangar is a variable in calculating ag payout.

Matchmaking is a weird algorithm. Buckle up

Pix relies on having you wanting to play at the top in Champions League.

Pix wants your win loss ratio to remain around 50%.

It takes into account your league cup count as to whom they make you play against.

They dish those out based on how you faired in the game. Subtracting if performing poorly adding if performing well.

Pix wants you to rise up in the leagues so they will generally dish out more cups for wins then what cups they subtract in the games you lose.

This will match you sometimes against stronger players so you get beaten so you are tempted into buying "Meta gear" to help you compete against stronger opposition and thus also rising up the leagues.

Having an extra bot will give you greater flexibility with having counter builds and also match longevity.

Always remember Pix will keep matching you in games that will keep that win loss at 50% and keep pushing you up for a while before you will eventually level out somewhat. 

I manage to keep in Masters where I like to be by capping my upgrades and mainly using legacy bots.

It's all a psychological mind game with Pix trying to get money out of you.

If you think the fifth bot will make the game more enjoyable than do it. Personally i prefer more bot options during a game.

Not interested at all. I have about 100M silver and have not upgraded anything for a while. The simple reason is that I've noticed that when I level up my bots and weapons, I just get matched with harder opponents. Like I was hovering between 45% - 60% win at level 26-29. And at level 30 now with a Kid, Ming and level 8-11 bots and weapons I'm still at 45-60% wins. So I figure there is no reason to upgrade anything, just enjoy the game. 

I do like to help my team or squad win though which is why I'm considering the extra hanger slot. 

Just wondering if Pix matches the # of bots in your hanger with the opponent. So lets say our team has 27 bots, does pix make sure the opponent also has 27 bots in their hanger? If so, then I may as well save my gold. 

If you're waiting on a Legendary Pilot, keep saving. Lottery is a ?female dog?

Get the 5th slot. It is the best return on investment in the game (except for the 4th slot of course). Your arsenal increases by 20% and with it the range of options you have to differing bots for differing situations.

As has been said the MM does not appear to care how many, nor what level, bots you have (it did about 3 years ago, so be carful reading old stuff on managing hangers etc) but now its all about your performance in games. A fifth slot will improve that no doubt, so yes if you get a fifth slot and use it well then your games will get harder, but you will have a stronger better hanger. It's the way you progress in the game as a player, embrace it and keep shooting the red guys.
