While yes Vindy does employ many of the trappings of a typical looter dungeon crawler i wouldn't call it overly pressuring you towards the micro transactions. The people who believe it does have not done enough research into alternative means to achieve the same goal or do not enjoy the grind which is pretty much the point of Korean mmos outside of the gameplay. In fact over the past year I'd say they have lessened the pressure to spend in the cash shop with the additions of purchasable lv95 weps and armor +13 stones in the seal shop, reforging for guaranteed +15 eventually with grind and growth rewards that are substantial enough to get you started. Events often handing out paid runes regularly and the yearly max +15 coupon becoming bi or tri-yearly.
^A lot of those sound like issues pertaining to your computer set up rather than the game itself. I know plenty who don't have any of those issues and other like you with some of those but not all. You have to remember this game is from 2010 and is not optimized for the advances in computer tech since and some set ups have no compatibility for older software.
(they could optimize it for current tech but nexon puts like basically zero future investment in vindy right now)
The weird part is the fact they labeled it a "legendary ore" box instead of "legendary weapon ore" box like they did to separate the dulla chunk boxes. Is this foreboding for the future where they will never introduce a armor version of this box or just a typo i wonder.
Optimization is so broad its no wonder they have no idea what you mean. If you mean the ui its been improved so much over the past 3 years from its laggy release state. If you mean general dungeons they run fine if you aren't using a toaster. Load stutter when entering an area for the first time is just the way the game is programmed and you gotta live with it.
They do listen to feedback but only from kr. For example glaive lynn was going to get an utterly forgettable long awaited buff but the kr lynn players rallied to get them to buff her for real and they listened. From this point yes they do have character balances.
Counterforce was a bad idea i agree but you can get literally free +15 lv90 belt and earrings upgrade them a bit maybe build a dulla ring and be perfectly capable in lv100. Ya it takes some effort but why should it not.
Agree that 8 man should be an option or at least make it 6 man instead. 4 doesn't feel raidy enough.
QB requirements are like the bare miniumum if you can't reach them the boss will just get tickled by you. If you wanna enter with tickle stats play with your friends in a custom party cuz no one likes to deal with 0 damage people in a "quick" battle.
New players leave for a multitude of reasons. New games might appeal to them more, the combat isn't for them, the fact you have to work to get anywhere, important info is not presented in game like money making tips.
I do give them some respect for not falling to the whims of the community every time tho. The community doesn't always know best.
(ya support doesn't play the game hence they couldn't answer your question best to ask that in the discord)
