Its crazy how some people cant grasp the concept that regardless of the type of loot system you run, many if not most of your raid lockouts are not going to net you new gear.
You can easily go multiple weeks/months raiding every week and not have the gear you’re looking for drop, or when it does drop, goes to somebody else for whatever reason (lost roll, loot council,ect.).
If you were running in gdkp groups for all these lockouts you would actually have profited thousands of gold, rather than lost hundreds of gold from consumables under other loot systems.
You aren’t going to be buying gear every run, just the same you wouldn’t be getting loot every run on a regular raiding schedule. You can earn gold in gdkp runs at an equal or greater rate than you will spend it
