They're presumably talking in relation to Lost Ark players who don't have established rosters in which case it will take 2 months to Lost Ark Gold go between 1370 and 1415. I've observed a few late starters become stuck in the 1370-1415 area and eventually quit because of the sheer raw gold costs to make honing attempts.
Assuming the player needs the mats from chests, their weekly gold revenue is (2100-800) 1300g of Oreha plus 800g for P1 Argos. Considering the value of P3. it's actually better to buy P3 busses than to do P1 and we'll say that you'll make 2700 - 500 (box) + 1300 (bus price) 900g, which is more efficient than doing P1. The player also gets more mats.
GHLs have crashed , and players playing on one of them is going to need to keep all their other tradeable to hone so assuming 2200g a week they could save for honing , and a 30k total raw Lost Ark gold average cost using the 17/17/17 method, the player will require 14 weeks on one individual's Lost Ark gold income to make it from 1370 to Valtan.
Although this isn't the case however, as many have pointed out in this thread, SG markets Legion raids as the content that saved Lost Ark, and their own statistics indicate that 1415 has the highest retention rates for players. The argument "oh in the event that they could not handle x, then how long do they have to play" is ridiculous because most players are going be able to quit if you place players in boring parts of Lost Ark that have been shown to have lower levels of retention for long periods of time.
I think it's because WoW and XIV offer more modes of appeal compared to Lost Ark. It's true that if you'ren't playing Legion raids within Lost Ark, it's not a very good game in any way. There are some elements of a collect-a-thon but they're not great as well as have a quick ending (aside from the RNG-gated ones). The daily content (Una, Chaos, Guardians) is generally regarded as acceptable by the majority of players and not even enjoyed for Lost Ark Gold Buy its own value. Continuous alt switching and level gates mean it has an extremely weak social community.
