However, how many times we can change our sub-class ? Infinite or just once ?
Most important, can i turn back to my original sub-class if i dont like the new one, and kept my skill i learned before ?
For instance, i am a W/M, if i change to W/E, and hate it, can i turn back to W/M again and have the monk skills remained ?
Would like to try something new but still worry about that

Thanks in advance ~
