[Mega] An Ancient Journey of Redemption

So, since no one has started a thread speculating when the event will start, I guess I will. This speculation is based on the following assumptions:
1. The devs want people to unlock Revan who haven’t 7* all the or toons from marquee packs
2. Their tuning the date to make Revan available only if you’ve been “maxing” your farming (meaning 3x cantina energy refresh per day, 1-2 hard node refreshes per day)
3. You purchase the 50 shard packs, and you’ve gotten the free 50 shards from marquees.
4. 30% drop rate average from nodes

So, if you do a little math, each toon would need an extra 230 shards to be farmed to 7*. Bastila and Jolee came out first, and have double hard nodes, so I’ll ignore them. That means you’re really worried about Zaalbar (single hard node) or t3 and mission (competing for cantina energy). If you do 3x cantina energy refreshes per day, you’ll get on average about 10 shards for mission and 13 for t3. That means about 40 days total. Zaalbar is a little bit of a wildcard, but with one refresh you’d get 5/day, so 46 days. You can probably tighten down to 2 once you’re done with bastila and Jolee, so it’s not out of the realm of possibility to squeeze him out in 40 days as well. So, my guess is about 40 days from their release to hard nodes (sep 26). That would put the event timing as pretty close to Halloween. So, probably last week of October or first week of November.
As an aside, if you use these assumptions, you can estimate that purchasing these packs will shave 5 days off your farm for mission and about 4 for t3, 9 if you get both.
