Infusing is pretty expensive. For my 150 I infused only one ring, a bloodstone ring that I can easily change the stats. Both rings are then attuned which gives me 5 slots on rings, two on accessories, one on backpack (Non-infused) and 6 on armor, for 14. These agony slots are all populated with +10s. I make sure that all combinations of weapons have at least 10 AR as well.
You could go cheaper still and not infuse either ring, and put two +10s on your weapons.

Infusing your rings is not expensive…I don’t know where you’re getting this. +10 infusions are expensive, and you really should be using that money to get more ascended gear so you can use the cheaper infusions.

Infusing rings is cheap… it’ll either cost 750 relics plus ~7g per ring, or free if an infused ring drops (usually from a T3+ fractal daily). If you’ve got a 14 slots with 10ARs and you add one infusion slot to a ring and put a 9AR into it, you are able to downgrade 9 other slots to 9AR and still maintain the same total AR. It costs ~10g to upgrade a 9AR to a 10AR infusion, so this saves you ~90g. Definitely a worthwhile investment to infuse rings.
Also, you don’t need 150 AR… just get up to 135, and use the AR potion to add the final +15 AR.
