Since the wrathstone patch today I have noticed that when you try to activate a synergy (Triangle+Circle) during the animation of any other skill it will activate the synergy but also the skill on either triangle or circle on the next skill cooldown after the synergy, depending on if you press triangle+circle or circle+triangle. This makes it near impossible to execute a good skill rotation while trying to activate synergies. Before the wrathstone patch I have never had this issue.
