Map/boss progress is out of whack

The first obvious issue is how slow nexuses are, I just did my t16 on an irradiated map to get my 6/10 boss tree points and I am still at nexus tier 8 quest.

I havent done many breaches and i often have to struggle to survive the initial assault so even if i kill a single rare the breach closes soon after so I have 5 breach splinters

I have done quite a few delulu mirrors but only really have 80/300 splinters, I know you can delulu waystones but this is an annoying extra process I have to go out of my way to do so i havent bothered.

I ve done a lot of expeditions, got something like 4 logbooks, none of them had any boss inside.

I surprisingly havent found many rituals, done quite a few while leveling up in maps and only gotten those very situational crafting omens and that omen of resurgence which sounds like a great 2nd life but since they are so rare I havent used them.
And the whole crafting omen system feels like it requires extra research cuz it specifies prefix/suffix so I got to go look into which ones exist that benefit using the most. No boss omen.

So now i am doing t16s, 6/10 at boss points, 14/40 atlas points, lvl 89 and it feels I still havent seen any non map boss content cuz they are so rare or require a secondary separate grind from the maps.

I enjoy doing maps, I like that towers let you trigger extra events of your choosing but I still havent seen any other non map bosses and I feel you should be doing base versions before you are doing t16s.

Also to get 8/10 map boss points you pretty much have to rely on the RNG of cleansed maps which can be annoying since now you gotta scan the entire list of affixes since it includes tower ones
