SSF Casual weekend player experience

Had fun throughout the game, reached T4 in almost everything.
If there was a way to do end game crafting in SSF using Ritual - I would still be playing.
Even with buffed rare omens I haven't seen one whittling since the patch hit.
I have full Ritual tree, always using some Ritual tablets (although they are like 10x rarer than breach and expedtion ones - why?), using max rerolls, 80-81 maps - nothing.
If it's required to have more omen rarity on tablets to ever see one - maybe make Ritual tablets more common?
If that's the intention and they are supposed to be so rare in SSF - that's fair, it's an optional mode.
But as it is, it's impossible to even hope for them, so I don't see any goal in front of me to keep playing. If I saw 1-2 each weekend of playing, or had any way to improve my odds of getting them, I would be still playing to make my gear perfect.
No other end game activity is like that:
Citadels are spawning in threes now.
Catalysts are affected by quantity/rarity and can be reforged.
Essences are affected by quantity/rarity and can be reforged.
Artifacts can be farmed in expeditions, can be used to buy and recombine gear.

Ritual tablets mainly drop from naturally spawned Ritual encounters found on the world map
(and not from added Ritual encounters from tablets in difference to all other map mechanics) (as of version 0.21).

It is a bug most likely.
