well its up to you. cleric is better for more survivability but as a tank you'll rarely die...unless you have a crappy cleric in your party
and yea Vortex? has a rogue sub so you could do that for a change in pace and skills

or you can do what i did...get more than just 2h skills..
i got all my 2h/1h and am halfway through getting my axe skills ^_^ its just nice to switch around and play dual axe one day and back to 2h the next day.
also there is nothing bad about just being a pure warrior..it wont require you to farm sp at all...so thats great ^_^
