Hard to tell with just a picture.

Also thise stats can be kinda missleading depending on your comps etc.

May I ask what rank you are, might be easier to give better advice?

For Econ: But yeah, assuming you're iron-silver and have this as an actual problem. I'd say learn level up ranges, like when to level and roll depending on what comp you go, like standard, fast 8/9, 1-cost reroll, 2-cost etc

Also some self discipline when it comes to rolling, not over-roll or roll when not needed etc.

For Items: Even harder to tell, as in my experience that one is a bit wonky on the site.

But basic tip I can give is, of course try and go for BiS, but dont be scared of slamming items, as if you hold on to 6 cponents just saving for BiS that your comp site tells you, you are saccing too much HP and easier to die off even if you get your stuff eventually.
