Here's why,
There is nothing more that we need to have.
So the prospect of paying $3 for a 1% chance at an item that might improve 1 character's overall damage to kill 100m HP MvPs in 10 seconds instead 15 is just so irrelevant. (Using the TLAP Drake MvP as an example here)
Ya'll know if I told your parents you spent $300 to get a ring in a video game they'd disown you or send you to rehab.
I'm not saying that I've never spent money on WPE. I have a few long-standing accounts that I renew with 6 month VIP promotions every now and then. I'm not saying I'd never spend money on WPE or boxes either. I just think its really silly to pay so much for such insignificant ROI.
I have noticed a decrease in the number of people that are selling items from OCP boxes over the past few months. Some boxes are worse than others, of course. But regardless it seems that with the reduction in population (supposedly due to ROM) the whales have migrated. Perhaps they are not seeing good value out of the new benefits items offer (as absurdly powerful as they are). The value isn't there anymore.
Multiple factors of RNG kill my interest as well. Thank goodness accessories, mids, and lowers don't have refinement requirements. If you were to calculate the average cost (in dollars) of an item to find it and get it to the correct refine (+10 is the new hotness) its almost impossible to rationalize doing. Even the flex threads have not surpassed 1 page in length for people sharing their results in months.
Box rates and prices clearly need some serious attention. OCP had a good run but we need a new system to deliver strong items that players want to get at a reasonable price. Like any consumer we want something that is effective, accessible, versatile and that we can get a long-life out of. The current system is ineffective, random, narrow in application, and is replaced in 2 months. Remixes are inefficient as well. Even if you bring back every remix there are too many options and as a result people don't know what to go for. We need a better catalog for these items.
