I would really like to see a way you could exchange unwanted resources to gain better ones particularly in regards to ascention materials. Something along the lines of 10/20 x 1* items combine to make a 2*, without the long wait and cost of the alchemy lab or it would make the alchemy lab worthwhile if you could select the exact item you want to produce. I currently am a level 50 player but I have six 5* hero’s that all need a 4* tome of tactics to ascend and it has been over 8 months since I got one in a Falhome pass quest, I very rarely get them or have the chance to fight for them.
Alchemy lab with do what you want. Sorry the game is a marathon not a sprint.
I have been playing for over 4 years hotham so I know it’s a long game, alchemy lab doesn’t let you pick exactly what you want to make and if you have levelled up your buildings to maximum you have obviously put a lot of time and effort in so you should have more choice is what I’m trying to get at.
