Why are there diminishing returns for obtaining skill points past level 20?

Every time you "level" past level 20 to get a skill point, it takes more experience to get the next point. Why? All this does is force people to create additional RP characters and go through the campaign repetitively another time because it's faster.

It's the way it is. Makes unlocking every skill with one character a lot more difficult, which was probably the intent here, to not have every single class available as a secondary profession.

a suggestion i made was to freeze it at the 20 level or even roll back to a lower number of experience points to get a skill point

or maybe open up all the quests for resuse by your new secondary profession

i think they will have to do something soon or it will be impossible to have as stated *all the skills of all professions*
