They could always implement haste in a totally different way like for example make it a very long cooldown spell that resets the target player's cooldowns obviously not effecting haste itself or there would be shinnanigans. Though my only real issues with haste were that on gear they became > everything else and on RDM it was another spell you had to cycle throughout a battle. If SE gave RDM hastega this time round it wouldnt be so bad.
