Is there a way to reset your skillset ?

What if you fail at leveling and end up with a set of skillsets that was a terrible idea ?

What if later on the devs do some tweaking and your favorite skillset ends up a weak combo and you need to respec ?

What if you want to have separate builds for pvp and pve or for different roles ?

Yes, you can reset attribute and skill line points for a gold cost.

The DEVs already said you will be able to "respec" for a fee.

It shouldnt be difficult to switch between a pvp build and a pve build by just changing the skills on your skillbar.

TLDR dont worry too much, you wont end up with a broken character.

Excellent news. I'm surprised I didn't hear anything from haters, the swtor forums were filled with people hating respeccing and the possibility of having dual specs.

Yes respeck is in. Skill points and also atributes as I understand
However it cost gold, price might increase with use as in wow as it should not be done daily
You can change hotbar setup anytime

Konkle confirmed it will increase in price as your character gains levels.
