I noticed that I could go back to swordsman (or so UI elements suggested) after picking highlander at R2. Same with Wizard. Does that mean you could do something like swordsman > highlander > hoplite > cataphract > hoplite > cataphract? I ask because a skillet like cataphract isn’t available until r4 and if you went r4 hoplite cataphract becomes unavailable at r5 according to the skill builder. Does the rank system work differently than the class builder at http://www.tosbase.com/tools/class-builder/ ?
The class builder is outdated. Use the skill simulator instead.
The answer is yes. This was changed only recently.
And you can allocate skills to later of the same class.
The skill simulator has it updated that way as well.
However, some kCBT patches are not applied yet, and it seems there are some changes to the skills (scaling and etc.). So I guess this is for general preference, until they officially confirmed the status of the class.
