Write down the pros and cons of each race, doesn't matter what they are i..e love the tail (miqote) hate being small (Lalafell) then go with the one with the most pros or just have 2 characters that you flip between as and when in the mood for each. You never know you may like the new race better than both, I think with heavensward we get a free fantaisia anyway so thats one less to buy.
