the less reliant on squishy damage dealer you are, the faster you can scale up to POTD
POTD isnt as much about game mechanics as its about items and encounter knowledge.
As long as you leave yourself a way out in all fights or play a defensive party, you can start POTD quite early
But why would you want to? Even if a new player would eventually want to try out PotD at all (which isn't a given), why is it better if (s)he gets there more quickly? Especially when, as you say, it requires game knowledge a new player inherently does not yet possess.
I would have loved to start the game with POTD - if act 1 had a similiar difficulty as act 2 i would have finished the game with a party directly (restart POTD in act 1 instead of act 2) - however since the game was too easy for "hard" i restarted and played POTD at the end of act 2, only to stop the run at about the same point again and restart with a solo character - i prefer challenges! Thats why i havent finished everything yet, i know if i played a party i would get bored and die because of it (ironman always - naked chanter and until the first run to thaos were the exceptions) since i simply cant be bothered with the game if its too easy - while there are some bugs that make the builds i wanna play quite a bit weaker and i am waiting because i hope they are gone next patch (monk with triggered immunity bug... monk with torments reach bug... maybe chanter can buff his dragon thrashed next patch... that would be awesome)
my solo run didnt finish thaos because of bad spells, bad items and bugged talent (itemslots), started a group run (ironman potd) after that and finished the game with 150+ death - the game was too easy to make me bother about anything, if my MC hadnt been a 3 con mage i wouldnt have needed pauses outside of bossfights (4 tanks, 1 healer, 1 3con mage... no i didnt need the mage for the fights, he simply made the game much harder)
And i am not the only one who found hard too easy, i watched some streams when the game was released and one of them even went as far as changing it to POTD later on (as you know, not possible without tools or something) blind POTD... it wasnt that hard after act 1... quite some ppl played POTD blind on release on twitch.
Now... i only play solo potd ironman, everything else is too easy - maybe i will try a no pause full clear party run... but that would be too hard instead :D
