I don't often if at all hear people giving comments to these kinds of topic. i'm sure they're physical/mental benefits of playing this gamemode for me i would say finger stamina is the most obvious. maps back then that would often deplete my stamina is unsurprisingly surprisingly effortless now. mentally it keeps me active somewhat, hard to say for sure it helped with reacion time even though i have gotten at reading over the almost 2 years i have been playing ctb.
