The mmr system needs to be improved
You can read about all the details of the MMR system elsewhere, but the short version is:
You got larger changes on your alt account because you hadn’t done pvp on it as much. As you do more, wins and losses will change your MMR by smaller amounts.
eg: when you get big jumps because of a win, you would also get big drops because of a loss.
but the mmr displayed was the same for both accounts so why are my alt accs match ups easier+ more rewarding

It’s called Volatility, the less you play on one account the higher the volatility is, no two accounts are the exact same.

Easier? Human memory bias, or random luck. It could just have easily been perceived the other way around.
More rewarding (or punishing, if you lost instead)? Volatility is higher if you have not played on the account for a while, or if you are not hitting the predicted results (win or lose) frequently.
Volatility is what determines how far your MMR changes, win or lose vs the predicted result is what determines what direction it changes in.
