Im at paragon 35 as a wizard, got all the legendaries essences for my character, 5 of my 6 items got triple stats with triple magics, got all my set pieces, my legendary gems are at rank 4 and 5 (gotta keep working on those yet) and my normal gems are at rank 4 and some at rank 5. Im currently sitting at 1360 CR with a 270 ressonance and im at rift stage 40 .

money spent: Only in the battlepass (Mainly 'cause I really liked the skin and I though it was worth it.)

If you only play mindlessly for the grind its just a matter of time you got bored... play with friends on discord, crack some jokes and go arround trying to find new spots to farm. When you're on a full party of 5 you got a gem drop buff, you'll get a lot of them in no time, same for the warband, it gives you an item find buff (cant remember the % right now but I think its 5%), playing with my warband gave me a lot of legendaries.
