Easy.
Spend TP to replace a circle.
It starts at lv1 again.
Unless you level it back to 15, you can’t choose another one.
There, now if you want C3 in a tanky class, you have to gain 45 levels without your highest DPS skills.
If a class becomes trash in a patch, you don’t waste 300+ levels remaking your character from scratch. If you make a terrible mistake, you’re not stuck with it forever. If you just want to try something slightly different to test out a certain combo, you can do it as many times as you want. Yet if someone else finds out the sick new build, you can’t immediately copy it without an appropriate amount of effort, possibly taking just as long or even longer than making a new character if they scale the required EXP to your highest rank.
