As title. Right now, it is very expensive to play around with your character or build because the cost of Respec is very expensive. If you respec and don't like your new options, changing back means 2 Respecs to correct an error.
If you want to change from Heavy Armor to Light Armor for a gameplay specific reason (Light Armor = PVE, Heavy = PVP), or you want to change Crafting Skills (Provisiong = Enchanting) you shouldn't have to pay 20k. Well, 40k if you don't like the new selection of abilities.
One Respec a month gives players some liberty about their character. It gives us the ability to respond to your nerfs (published and stealthed in), and it lets us evolve our characters over time.
Within; Without.
