Russians were basically fighting with both hands tied up, they didn't cut down Ukriian's power, even internet is still up and running, videos are prohibited to avoid both Ukraine and Russian hatred mainly because even though Ukrainian don't see them as brothers but more than 60% of Russian still thinks they are brother in blood, Russian were good in psychological warfare but Ukrainian is taking all these advantages for their information warfare.
Secondly, Russia's poor economy has also shown its negative side as its large amount of old soviet era equipment can not fully comply with their military reform, and many more set back but not going to list all out here.
There is one pov among some military veterans that Russia has intentionally sent new conscripts to see Ukrainian reaction and their preparedness. Once this phase is over, and their Armour brigades are in desired position, better trained forces will move in to finish the job..
I am not sure if this is the case. But situation is too fluid.
