Yes, but what equipment? If you're respeccing at 25 all the time, I'm going to assume it's some heavy plate or possibly an armored horse. If so, compared to someone who WOULD pay upkeep, yes, that is a lot of gold. You would probably be in debt
(negative gold) if you had been paying upkeep. If I'm wrong and you're using light equip, what's the point of retiring at 25?
If you really don't give a damn about heirlooms, do this: Get to lvl 31, retire, sell heirloom point for 450k gold, then use whatever equip you frigging want until you run out of cash again and repeat the process.
