It’s a steady and low risk way of accumulating runes, but in the long run it’s not a high wealth generating activity as you’re robbing yourself of the chance of gambling for circlets which can really fetch a lot. Consider:
- +2 class/+3 skilltab with 20 FCR or 30 FRW magic circlets that can be 2 socketed
- Artisan/Jeweller’s circlets with 20 FCR or 30 FRW that come with 3 sockets which are BiS for a faith bowazon
- Rare circlets that are BiS for a WF bowazon and other characters
Where as for gloves, almost all casters will use some kind of FCR glove, which the options are quite widely available from uniques/sets.
BiS melee characters will most likely go for laying of hands, lava gout, steelrends, dracs. Again, quite widely available.
You might be able to gamble a 3/20 pair of gloves, but they’re not all that hard to get anyway and while they fetch something, it’s not a huge amount.
Sure, you can gamble some GG gloves, but the odds of doing so are astronomically low compared to the circlets above.
Also, note that gambling for vamp gloves requires a high enough character level to make this a meaningful exercise. Selling 10m gold can be done by anybody starting out and doesn’t require time to gamble (12 minutes or there abouts).
12 minutes is the time it takes to farm about 3 million more gold.
