I've found this annoying as well. However, the other filters are really good, such as filtering out ones that don't want your job, disabling lootmaster, practice or duty complete parties, to narrow it down.

I did take a look at this raidplan and, at least for me it seemed almost the same as Hector anyway, except it says left/right for vines instead of west/east, but PF can't decide on DPS or Supports first, N/S or W/E or BD, Relative or TN, RRMM or RMMR.

Really though, it doesn't matter that much because all these strat differences are subtle, except that TN parties mean tanks are running across the arena sometimes and it makes it makes B3 less consistent. The important thing is they actually say what their strats are.
