War Robots game play getting harder

I've slowed down playing Pixonics War Robots mobile game around October 2019. I started another mobile game from Plarium RAID Shadow Legends to give myself some game difference. I didn't give up War Robots altogether having amassed a tidy little Robots and Weapons. Just milking along on the daily advertisement viewing reward collection. And should I gather enough Silver Ag, I would upgrade an item. Mind you, the amount needed to upgrade anything was so exorbitant making it near impossible to gain any upgrade advantage. Coupled with the new Titan robots, pilots, modules, etc, it takes forever to upgrade anything! Thankfully Pixonic tried to give additional silver, but it is never enough. It still takes forever to upgrade! Period.
