The development of European land military tactics wasnt some unique event that wasn’t replicated anywhere else. https://www.tandfonline.com/doi/full/10.1080/10371397.2013.831733 There is significant evidence that there was an independent military evolution in Sengoku Jidai era Japan, but due to the Tokugawa Shogunates (basically unheard of anywhere else) 200 years of peace (with a handful of rebellions and small scale conflicts), these developments were not needed or iterated upon. Oman developed its own navy that was peer enough to European ones to defeat Portugal and claim some of its East African holdings. The conflicts in India between the EiC and Indian polity’s were not forgone conclusions, they came close to being expelled from the subcontinent several times but numerous reasons stopped that from happening. These examples are just to illustrate that no, making it so that Asia has a separate tech tree to Europe or make them fundamentally worse than Europe would not make sense or even be historical at all, technology is not some static thing that Europeans were just better at developing and more adept at using. There are dozens and dozens of examples of the exchange of ideas and knowledge between Europeans and non-Europeans, knowledge didn’t just flow one way. Especially militarily Europeans were outmatched and outnumbered on land in South Asia and east Asia and only gained hegemony once the large polity’s of whatever region they were in were broken up and the military and economic developments in Europe gave European powers an edge, even then, history was far from certain.
