I started playing paladin its been two weeks now , and i don't know if changing some best in slot stats will affect my tanking that much.

To be fair i played mmos with very little GCD and i found ff 14 GCD way too slow , i know the game is intended to be played like this , but i would like to change my GCD with skill speed , since its way more fun for me to lower it , so i decided to buy some item at level 60 with all skills speed and it was very noticable at my level , and i wonder if its a good idea to get skills speed if i reach max level and if its realy bad to keep focusing on it.
