As the title suggests, allow us to remove these gray arrows as they cause decreased FPS performance. Swapping over to 3D is not ideal as the 2D minimap is much more useful in determining where potential enemy players are located.

Do the quests at the Grey markers and they all disappear.  The grey markers that are not quests are kill tasks, go to each monster node and do them.  Then abandon all quests you are not actively doing and they all disappear.

It's not like the grey arrows are there for no reason.

I've played the game for almost 6 years now and I didnt know those arrows showed quest locations until I checked them after reading this thread. They are deffo there for no reason.

Hover over any of the arrows it tells you exactly what the arrow is for.  Every single one has a reason The only ones I don't have anymore on my main are the Boat kill quests.  There are none that don't point to Margoria for me.  

The guy asked for an option to hide them. Noone cares why they are there, they are completely pointless anyway.

As an endgame player doing those kill quests is a waste of time and silver. I am currently 701GS and can't be bothered to kill 1500 Hexe Sanctuary mobs to remove 1 of the many littered gray arrows on my 2D Minimap. If that is any indication of how long it will take to remove one single gray minimap arrow then the endeavor may take longer than it took me to get 20% ecology, 7K family fame, or the compass, map, and both infinite pots (exaggerating but you get the picture). I was willing to waste time and silver to complete those treasure items and bonuses such as 8k eco for 20% item drop rate and 7k family fame for 1.5% return on CM. I am not willing to spend 20-30 hours just to still have minimap arrows remaining in the fucking sea.

If they bug you, you have a way to remove them already.  I was trying to help you and you instead snap back like an asshole.  Getting PA to change it is likely not to happen.  I guess telling someone what they can do currently is not wanted.

Removing them via completing the kill quests/swapping over to 3D map is not what I want as stated in OP. I want them to add the option in-game to be able to remove those annoying arrows. How hard could it possibly be for them to this change? Their poorly optimized game already has one of the worst FPS/desync experiences in NW/Siege and in general. How about changing small things to make it more playable? Nobody at endgame wants to spend 20-30 hours completing kill quests around the map in order to remove these gray arrows. That's 15 billion silver + potential wasted grinding low-end spots for something that should be an option to remove in the first place.

Why should PA do something you could do yourself, stop being lazy.  

I mean with that line of thinking, your suggestion for the CM is also redundant since you can already buy items to your max weight- stop being lazy. 

it's an annoyance and a sight for sore eyes that you should be able to just turn off.
