I've played a few different role playing systems now, Ascendant Destiny is by and far the most balanced and offers the most freedom in character creation. When I started advancing my second character, a gnomish engineer who primarily used rifles and technological versions of a few spells, I realised he was lacking in close combat abilities so I branched out and learned how to use a dagger and stealth. Your character isn't confined by early decision and you can advance them as you please and as best suits the party dynamic. The dice system is very satisfying as well, as I level up my skills is allows me to role more dice which makes you 'feel' more powerful when using certain skills, it has a very tactile satisfaction to it while still being balanced and amazing fun.
