Rotating Game Modes: Variety is the spice of... LoL?

When Rotating Game modes first came out, there was something different every weekend, and some players have come to look forward to this change of pace. We rarely see URF, mirror mode, and poro king. Now there have been 2 weeks back to back of the same thing, i.e., Nexus siege. The lack of rotating is especially disappointing when the mode is, well let's just say less entertaining. If the rotations reverted back to weekly, instead of 2 weeks, there would be less disappointment.
