Your biggest features that would Ruin POE2 if they took inspiration from that other new ARPG

Don't think GGG has the need to attempt to copy lost ark like this other game as the company is creative enough to even survive as a f2p game for another decade with ease. But that's not surprising at all giving that the company of the other game priorities profit over content and gameplay. Some cutscenes around a crappy lore ain't everything after all

Low enemy density and low impact spells.

And long, boring dungeons that make you think twice about ever starting the game again.
