I'm a "whale", did Zenith last month but skipped it this month. Not because of the event itself (I find it pretty interesting, just like the draft mode on clash royale), but because of the time frame. I'm not going to skip Sage, GNW, or a ton of Sun Coins from 9 Tails to do Zenith, there are just so many other events at the same time, and the reward is generally not really worth it. (Plus I'm usually still working when it starts. But that a personal problem.) 3K coupons if you win all 8, but that is already hard enough to do while trying to squeeze it in between all the other events. In reality, the majority of people aren't getting that many wins. Plus having to make sure I have at least a 30+ minute window clear for each match is a lot to ask. If it ran the same time period as Bonds, I would probably do it every month. Otherwise unless I have a lot of free time, (i.e. get off work early) I'm skipping it. It's just an added stress that I don't really need for a potentially mediocre reward. In the same time I spend doing it, I could just work and then do the $100 recharge which has a higher guaranteed return.
