warrior epic is both 1hs and 2hs. it has a scabard that will turn your 2hs into two 1hs weapons.
a smart warrior/tank will have/keep all his weapon skills maxed other then h2h unless you are a monk/BL.
focus on your 1h skills like 1hs, 1hb, and piercing but do not let your 2h skills get to far behind or it will be even more difficult to max them out.
harsh being level 50+ with a 40 skill in 2hb or 2hs. your not much of a tank at that point and are more of a hinderance then a plus to your group/raid.
