Aggravated at defeating 5* titans and the loot being 1 and 2* items…
Get Used to it, the good stuff doesn’t really start dropping much until tier 9 loot which I think is when it switches to 3 ascension mats slots. There is a plethora of threads about it on the forum.
The loot is random, but you get more ascension material slots for higher level titans/better performance.
I’m often getting loot tier 11, and sometimes only 1*-2* materials in it…
Keep killing those titans, good stuff might pop up next time!
