No 2 won't happen as far as I'm concerned. Vengeance Systems is the game signature identity. Altering how MR works might give a negative impact to the game.
No 3 is a super duper great idea! I also want to increase quest exp specially in lower levels. This game has a lot of high level people making it hard for lowbie to find a grinding party. So I think higher exp for quest is a great idea. I don't mind the gifts tho, they have event for that.
No 4 I think they already had that event, I'm not sure if they're going to have that again.
No 7 Yes yes! I'm also tired of my character's look
No 8 If you're going to read forums, I think they already boosted other characters.
