Is the tft ranked ladder easy to climb? (Compared to league)

Hey guys im playing tft for 4 weeks now and never played a game like this before. I managed to hit platinum after 80 ranked games.

I also hit masters in League after playing it 10 years but I remember that hitting platinum for the first time required me to play several years and even to this day there are many people stuck in silver / gold despite their experience of 5-10 years playing league.

However hitting platinum in tft felt pretty easy and I still feel like I do know nothing about this game. I mean I definitely know 1000x more than my first two weeks where I was absolutely lost, but its not like I know what I am doing.

So I wondered is the ranked system in tft crazy inflated?
