The patch notes claim we no longer pay upkeep below level 25. Of course I immediately decided to see how I might exploit this to wear expensive gear all the time. Forever a peasant, but a very well-equipped peasant! This is a rather silly idea so don't have a stroke whining about how bad it is.
Level 25 is about 1.58 million experience. The idea is to use the respec feature to de-level each time you hit level 25, costing you 50% of that XP and dropping you to level 21 again. Ideally we want a level 21 build so we don't have to fiddle much with our gear, so I propose this:
Strength: 14
Agility: 15
Skills to attributes: 6
Power Strike: 4
Shield: 4
Riding: 5
Weapon Master: 4
You can fiddle with this as you like, but the goal here is to have riding 5 for a charger and 14 strength for reasonably heavy weapons and armor. You can carry the following without ever paying an ounce of upkeep as long as you retire as soon as (or right before) you hit level 25:
Great Helm / Litchina Helm
Churburg Cuirass
[Polished] Gauntlets / [Gilded] Hourglass Gauntlets
Plate Boots
Heavy Lance
Longsword
Knightly Kite Shield
Charger
Of course it's possible that you'll have to pay upkeep even after you respec, or that chadz will now fix this now that I've mentioned it, but here it is. Enjoy! (Or don't and go away!)
