Skill Gem Suggestions

I made myself a character and i am looking for some advice on gems i can use for progressing as i level up, currently at 36. I am focused on STR only, using maces as weapons. Ive gone for a full Health and Armor build, leech, and duel wield.
Build is based off of Duelist Champion. Currently i have Earthquake as a primary, but im looking for suggestions on skills and what to link with them.
I am reasonably new to the game and have done allot of searching but it seems like most builds cross over into dex and int to create links. Will this be possible or am i going to have to start branching off to dex to help me have access to other skills and supports.

Looking forward to hearing what you all have to say.

Thanks
