EDIT: Alternatively, if you are solo PUGGING, then you're the token "Pro Player" to help pull up the Elo of the "Average" team... which happens very often. Either carry harder or drop with a premade (unfortunately...)
I'm going to explain how Elo MM works based on my observations dropping with various people of high and low Elo.
If we assume that:
1. Player Elo goes from 0 - 10
2. New players/weight class start at 3
3. Team has a total of 3 units/aggregated score of lance (for ease of calculation and illustration)
Why you get matched up against Lords / SJR is because your Elo isn't high enough.
If we assume Lords / SJR to have Elo of 10 (because they fail to find matches and we know they have a big gap between their Elo and the rest of the players)... This is what the match maker does.
If only players of ELO running from 3 to 6 are around when they form a premade and drop:
Drafting Lords/SJR/Pro Player Team
Lords/SJR/Pro Lance - 10
Noob Lance 1 - 3
Noob Lance 2 - 3
Total: 16
Drafting Average Players Team
Avg Lance 1 - 5
Avg Lance 2 - 6
Avg Lance 3 - 5
Total: 16
Now, that assumes if we manage to get equal Elo.
However we know that as match finding takes longer and at hours that not enough pro players are on, or searching for matches at the same time... you start to get weird match ups.
If Elo rating of 5 was the maximum.
Avg Players Team
Avg Lance 1 - 5
Avg Lance 2 - 5
Avg Lance 3 - 5
Total: 15
If Elo rating of 4 was the maximum
Avg Players Team
Avg Lance 1 - 4
Avg Lance 2 - 4
Avg Lance 3 - 4
Total: 12
You'll see that you're stuck in "mid range Elo Hell" actually.
The match maker is unable to get enough "highly skilled" opponents for the pro premades and throws what they can in there. Since you are slightly above the average, congratulations, you get thrown in.
However in Reality...
The pro players will mostly be ranked highly at the 80th or 90th percentile and not at the hundredth percentile because they still lose some matches from time to time (mostly due to base cap or sheer bad luck) and that dents their Elo severely because they are supposed to win that match. This means the players put on that team wouldn't be that nub.
You will also observe the further up you go in Elo, the more you're paired up with poor players to "balance" out the Elo depending on the amount of players active and searching for matches. On good play times when there are a lot of players, you get challenging matches and the matchmaker works great. On bad play times you'll want to pull your hair out while you watch Trial mechs run around in 3PV like headless chickens.
When you Elo gets high enough
You become the anomaly in the system and you start nub bashing and ride the PPC pop tart train. The best way for you to realise this is somehow, get yourself into a drop with 3 other top players and observe the massive differences in skill.
Some Screenshots to Illustrate
Simply look at the damage and the mech chassis/variants.
