Remove Shatter and Secure from the rotation.

Only partially, especially in FLs because FLs turns into a zerg where crowd movements tend to always follow the same script. I have played old Secure, it was exactly like this, with the exact same patterns every time. This isn't a hazard that current Shatter also always plays the exact same no matter what. There is some replayability in the fact that yes, at the micro level you'll move differently which is already a huge gain compared to the pve we're getting, and if that satisfies you, then that's great for you. I however see zero negative with having adjustment and some rng at the macro level to shake the script and change macro patterns. This is what makes Seal Rock and Onsal better to me.

So I do indeed stand by that opinion.

The crowd movements don't really matter as an individual, you can single out enemies from crowds and this is partly where the fun comes from. Plus crowds as you mentioned them vary greatly from game to game.
Also the node rng allows diversity.
