In the end, I made so much dusts, I didn't count it anymore, while finally having nearly leveled up my Tyrannitars to maximum (alas, candy....) and some more. Ah well, I still regret that I had many things to deal with, I wish I could spend even more time on lure centres and use every Star Pieces I have.
The multitude of spawning Pokemon with low candy requirement to evolve also makes it easy to stock candies and do more frequent Evolve session.
Also, this time a 14-flat Mewtwo joins my rank. This is the highest yet, only lacking 1 IV point in each stats. But what mattered more to me was the golden berries I need to feed my defenders in another small town I came and left few days ago and ward off spoofers. And also rare candies I may use to fund my other legendaries like maxing Raikou for possible future Vappy raid (hopefully during Regirock raid time).
With rumours on future overhaul, I hope Latias will have a place in the future meta I have been catching a lot and as of now her use is only for potion efficient attacker (itself is horribly inadvisable in spending resources on), Dragon-type quest fodder, and a great defender that can't defend by default. Sad, since I love her, and had been seeking more of her....
Also, I run out of Fire-types now. Flareon quest is not easy to find, but not that rare either. I don't know what I should use, other than hoping for Achamo / Torchick? to catch or hatch, stocking up Charmander soon, or using up my Houndour? candies and Houndour quests (Gym battle 1x).
Still, the research feature had been such an addictive success, I couldn't stop completing quests like a fantasy mercenary.
