A lot depends on timing and skill selection, rather than just going through a set 'rotation'.... especially when fighting melee opponents. Be very mindful of when to best use your CC. Try never to use skills like Shocking Touch, VI a Fulgrite Stone or Shocking Words when your opponent has active immunity to a particular type of CC.... you'll be wasting some of your best opportunities to gain separation. Typically, use smaller CC skills first so opponents waste pots on something like Shocking Touch instead of Shocking Words. Also, perhaps try riffler swapping. It can be done in combat, and the right riffler and PtH makes it exceedingly hard to keep slows on an RK. Lastly, avoid using AotE in 1v1s. It's an OP skill, and if you get to where you rely on it to stay alive, it will hinder your development as an RK.
