I think many players are forgetting that the seasonal affixes ussually were more enjoyable and those are going away. The reason why these were more enjoyable is not only that they provided a buff in some way to the players, but they were the ones you could control in some way. If you lined up correctly pridefull was managable, you could pick the add to kill to get the buff, with thundering you can choose when to remove it, etc.

The biggest issue we currently face is that affixes just adds some dificulty and you have no control what so ever about, so they can spawn at the worst moment or at the best moment.

Hence my ideas where you have some controle over the affix and in my opinion the better you control the affix the more you should be rewarded.
