The key to getting the most out of any weapon combo is to switch elements after using skills that have longer cooldowns. These long cooldown skills are typically on your 3-5 keys. Your 1 and 2 key skills, although on low cooldown, don't prevent your opponent from damaging you, which is not going to help you survive. Also, although they can be spammed they typically do low damage, so you end up mashing your 1 key for very little gain (the plinking). By switching elements frequently you ensure that you always have a high value ability to use, becauseuse; while playing around withoutwith another element all of your previously used skills are burning through their cooldowns. Elementalists are blessed with lots to do while a particular skill is on cooldown (20 weapon skills versus the average 10) - take advantage of it.
