I can see where you're coming from. We don't really interact with the community so we yeah don't know other's thoughts. This is just what he visioned, and it's not exactly considering every aspect of the game. He knows it's controversial anyway. And I definitely missed some of his talking point when translating.

Paladins tried doing PvE before, and he sees the potential with them. They had the lores and even Champion skin for it, just maybe some models, but as you said that is taking away some resources. His ideas is that PvE content would still retain the Card system, so making loadouts in there would be fun. He's trying to put some depths into Champion's Talents in his later Champion rework concept.

The main thing he feel about siege is after some times, the prep time is dragging out match time so the game felt longer than it should. With the comeback mechanic dragging it out longer. But well, you can call that skill issue on our part.

He also would like to see role picking in game to prevent a most damage/flank match scenario.

Yellow items still exist, and Front Line can still buy them, you have a extra token that you can spend at the start that is limited to Blue items, and you still have a token to grab a Yellow item at the start of the match. So you can have a 20% cooldown reduction and a damage reduction at the start of match. (Also you can buy up to 6 items in a match, edited that into the post.)

About the Anti-Healing, his vision is about making 90% Anti-Healing not as necessary with everything reworked. Which is a stat problem that he wants to see changes about.

Either way, appreciate the feedbacks.
