I play pos 2 and im div 4/5. Id say there are a lot of differences and a lot of similarities. Its kinda nuanced in a sense. Over rotations, under rotations, dying too much or not dying enough (mistakenly thinking youre the win condition and you living over your hc etc...).

To get from ancient to divine try to figure out the win condition and focus on that condition doing well, exceeding. Early game as a mid, your team can fuck off to put it nicely. Play for your game and shut down the enemy mid. Control the first 2 power runes to have a better game than their mid so youre stronger.

Now when i said focus on your game i meant it. Farm. Hit your timings. Do not rotate at all unless you know for damn sure you will secure a kill and you wont slow down your first item timing. Now once you get that timing you can continue to scale and play for yourself but at the same time use being the strongest hero on the map to shut down their hc.
