No way to get omicrons now without pay2win?

Right now I have completed everything that is doable (mostly) f2p, and I'm at tier 4 + (2825/5000).

I have Huyang at 65 shards, which means I have 3 / 4 of Tier II of the GC. 

I have 2 / 4 up to Tier X of the GC. I realize not everyone will be able to do this though, without Saw or Luthen, but mostly everyone should at least be able to get 1 / 4 on Tier X and 2 / 4 somewhere in the middle tiers, if they had a shot at GCs in the past. So that means  2425 less episode points if you made it to Tier VI (the non-relic tier), meaning you should be at Tier IV now regardless.

I have easily completed all but 4 of the Huyang quests (and the remaining ones aren't hard either), but that won't help me since I am not getting the pass. I am hoping they will make changes to give some reward for completing all the quests without the pass, but that's just speculation.

I expect to be able to buy enough loot (omicrons) by the end of the event to not complain loot-wise, but we will see.
