The upgrade times were already way, way too long for a mobile game. With this change they're absurd. At 2 months per item, or longer, and having to do 3 to 5 items to level a single bot with weapons we're looking at what...advancing less than 2 new bots per year? At that rate, for many once their current hangar is no longer competitive they're pretty much done. There's just no way most will sit around for months to advance a single bot into their hangar. It's simply not a reasonable method of moving forward. This is not an improvement in the game, or the experience playing it. This only serves one purpose, the monatization of power within the game. P2W...nothing more, nothing less.
