I hear at lvl 20..

I heard that at level 20 you can change your second profession. Well I was wondering, can you change it more then once? I got stuck with my second profession when I accidently completed a quest for it not realizing that it would put me into that profession. I am debating on whether to switch to a War/Elm or a War/Mo I am a War/Me no. Any help would be appreciated. I want to be an effective tank and still be able to deal some good dmg.

it's not exactly once you reach level 20, but once you ascend, but those 2 events usually take place around the same time. but yes, you can change your profession and you can do it however many times as you want. and all of the skills that you've learned are kept so if you decide to switch back you'll have all your skills from that you've learned before. and I'm a W/Me that took the Memster quest by mistake too lol.
