Suggestion:High Curse costs for PVP Mode only?

The 0.9.13 Patch doubled the curse cost and decreased the Temp Chain effect. The idea behind it is obviously PVP.


But why not add it as something like a map mod: "Curses got double costs"?

When leveling towards a level 28 PVP character curses are really expensive and several builds are unable to pay those high costs unless they reach higher levels.

Level 28 PVP builds already go good equipment and high level characters don't care about mana costs anymore. But if play PVM and you won't be able to curse at some point because you need the remaining mana for combat skills.
