I don’t disagree with you that a Tier 8/9 raid would be good/fun/needed for the Pit (some guilds are probably ready for a Tier 8 HAAT, btw), but me personally I’d like to see a smaller mini-raid event - like tackling the AT-ST but open to more than Ewoks - to keep the whole guild active and engaged on off days when there’s no Pit or Tank raid
Less raid tickets to start it, two to three phases only, easy to crank out 1 a day or up 6 a week, and rewards dedicated to mid-level Gear that’s annoying to farm like the Mk III Holoprojectors or Carbanti Arrays that everyone needs 50 of. Save big gear rewards and rare shards for the big events, but something fun to work on in the meantime. Especially if there were variables like some days the raid boss was faster, or had higher tenacity...
For what it’s worth my guild is in the same boat as you though - Heroic Pit in 20-30 minutes, and cranking out nAAT no problem, but we have yet to beat HAAT.
