This isn't commentary on The Sieve, which I've mostly found to be a fun activity, it's that being on cooldown 75% of the time means when I feel compelled to run a Sieve, I usually can't. I'm not sure if the point was to make The Sieve feel special, or to encourage players to go into the Portal, but the result is that now I almost never check Kepler to see if The Sieve is available. The loot is good, the activity is mostly fun, I'd like to run it more, but it's like a really good dry cleaner who's only open three hours a day on a rotating half hour schedule - you don't go to that dry cleaner. I'm not sure what the experiment was intended to accomplish, but as a player it hasn't really worked for me. The rotation is more of a deterrent than an encouragement. Please don't put Renegades' seasonal activity on a cooldown, and do put it in the Portal, or at least put it on the Portal screen.
