I recently dropped as low as possible, which turns out to be 60 trophies. I have been playing around with teams and matchmaking since then. Nothing all that surprising to report, if you play a trophy appropriate team level, you get decent matches, if you go to extremes (like when I put in my L30 team at 150 trophies) you do get things close to your team strength, but can generally smash anyone. Conversely, when I was dropping and put in my lowest level team at my highest trophy count I got crushed, but by much lower level teams than the trophy count would imply. To me it seems that trophy count matching kind of restricts team strength matching, but only at the extremes. Once you move to a balance point, the matching gets pretty even, but only on team strength. Trophies seem irrelevant after a while.
Now that I’m climbing I can say this - the garbage starts to pile up in Lockwood. That is to say, overboosted dinos and DC. Unsurprisingly, the most boosted dinos I’ve come up against are sino based legendaries at this point, by a mile. Mostly utasino, but some allosino, and even sinoceratops itself. Other than that there has been some gorgo, purutaurus, t-rex, and smilodon.
