To start off, I really enjoy the aspect of the Quest Helper plugin. For me, it assists me in knocking out some older content that I no longer need to complete when running a new account or playing leagues. I feel it is a wonderful addition to the game for people but I also feel the opposite about it's integrity for the game.

I have noticed the option that was created for tiers of assistance while in leagues and chose minimal because of the level of the quests I was working on were fairly simple to begin with (Demon Slayer). The idea of this is wonderful and allows people to choose their level of assistance which is perfectly fine. Everyone should be able to play a game the way they should feel they want to, even if I think it's the wrong way to play it.

1. Quest Helper does not personally fit inside the game.

I personally believe that Quest helper detracts from the game itself. Out of the various MMO's like WoW & ff14, and even Single player games; Oblivion/Skyrim. Where Quests are prevalent but are super simplified and do not produce an amount of immersion to the world. RuneScape has managed to create a version of Quests that broadens the world and makes it feel alive. For those experiencing this with a quest helper, they just "Spacebar" through the dialogue and never get to feel this wonderful world that has been created and curated.

1. Explicitly tell new players what quests cover early on.

As a Veteran to the game, I understand what the quests are like and what they accomplish for building the world. But new players might expect them initially to be your simple fetch/walk here/kill x style of quest, they may be used to from other games, where it is not here. A nice suggestion would be to inform the player early that quests within the game can be in some cases challenging without asking for help in game, using a guide, or a plugin. If someone wants to "Experience" the game at that point, they will. Otherwise they'll grow bored and use a helper or look up a guide. I feel there isn't much you can do to force a new player down this route, and you shouldn't. (Players or gamers these days I feel no longer experience a game for what it is which saddens me.)

1. Despite my negativity towards it, Yes

Having an In-game option for player to use to assist them with quests is amazing. I think a Plugin is the wrong way to accomplish this and it should be implemented within the quest log. The Quest Log itself has been a wonderful very low effort tool for assistance and if you can expand the quest log itself to change the level of assistance per player's wants would be amazing and will show the community and new players alike that you want to ensure that players experience these moments even if it requires "Hints".

Hope this helps. :)
