I agree with you about a "balance", but like always not all is fine for everbody . So i prefer the option to try with differents options and see what happend. For example, now only I have 2 C5 in testing mode on my A5c, so what happend if I play on my PC? I have between 15-20 ms more of ping than before,( 8 ms SRS timeframe ) and also i feel when the A5c is moving from MCS7-6-7-8, etc. For that should be an option as well to fix the max MCS, not always jumping. You can see on my another post that my parameters are very good to have MSC7 even 8, but most of the time is on 7 or go down to 6, and belive me playing FPS games for a long time ( over 20 years ).
I now that A5c is constantly checking all those parameters due to not all the time you have same conditions, noise, signal, etc. but as before in my situation all parameters seems OK to have all the time MCS7. In resume, maybe is a good idea to limit MCS6 ( lossing very small performance ) but taking more stable conecction.
