I am incredibly disappointed in the drop rate of 2/3/4 GA items almost non existent on torment 4 at 275 paragon points, and even while using obols the usual drops are 1 legendary item and anything up to 32 other items of rare or even magic quality.
Once you reach T4 you shouldn’t see blue or yellow drops they are pointless, and as for mythics and uniques both are easier to drop than a 2GA item though as neither can be tempered 1GA items are more powerful for builds in almost all cases. As for 3GA or heaven forbid 4GA items they seem ridiculously rare to the point of non-existence.
Diablo 4 have had this equipment balance problem from day 1 they keep adding in new seasonal skills to create power which continue to cover up the basic problem lack of proper scaling in damage , defence and ability of equipment.
