It’s ok as you’ve got nothing else to spend silver on except equipment and attribute points at endgame.
So it’s actually helping the economy very much if the players spend their dozens & hundreds of millions on Velcoffer instead of flooding the market with it.
After watching the Dragon Nest economy inflate like a baloon over the course of 3 years, IMC is still very effective in collecting the silver from all kinds of players while not destroying the overall balance that much (if we exempt the +40 weaponry).
As long as people are happy with marginal improvement, that’s fine.
In my case, I’d rather spend my millions on buying attribute points to max the attributes for Exorcists Rubric&Aqua Benedicta than wasting them on “potentially better equipment” that has too much insecurity in it to be worth the time&ressources spent.
Especially considering with how many others you have to compete with for the scarce resources[i.e. good armors/ichors/recipes].
Sure, the improvemt is costly (~200 million silver from level 80 -> level 100), but it is absolute and is a complete progress for however long your character exists (i.e. including future Ranks that provide better equipment options); i.e. future-proof investment.
Also, 20% more damage is not a shabby thing, that’s 1% per 10 million spent.
In contrast, by ruining your bought equipment, you lose several dozens of millions for recipe, practonium,possibly materials and the ichor kits or at least several dozens for an item with 3-4 green stats, sierra dusts and ichor kits.
That’s 0% improvement for up to 200m or more each ichor, unless you’re not using Solmiki, thus not losing equipment set boni by exchanging the specific items one by one.
There is no point in quickly getting the new gear. Velcoffer will probably stay relevant till Rank 11 or 12, which is until 2019/2020 (if the game survives so long). That said, there’s still a time frame of over one year to get the items slowly after improving everything else first that will stay on your character (i.e. attack attributes, status points,levels,etc.).
