Grenades arnt hard to dodge at all
No of course not, unless you just happen to be under suppressive fire and slowed... oh wait....
There have been several big changes to the infantry, but the point I'd like to make is that each unit has its own merits/uses. Its not like you start spamming KCs when they're available and forget Grens. Nobody does that!
A resilient unsuppressable unit can do wonders when you need to hold ground or cap a contested VP under fire.
While I'm intrigued by the changes you mention, I also find it an unfair comparison to KCH. First of all, alot of people do forget about grens once they get panzer command and it's not always the bad players.
Guards can't be compared to KCH because there will always be a need for grens to provide backup AT, which KC can do only with the inefficient faust. Guards provide AT that strelky simply cannot, making them much more multi-purpose in late game. Guards also have drastically more health than a strelky squad, whilst KCH actually have less health than a gren squad. KCH also cost alot more to buy and reinforce, in manpower and time compared to guards and their respective mainline infantry.
Also comes the fact that a unit effective at long range becomes exponentially more powerful with numbers, as opposed to short range weapons which becomes linearly more powerful. For example, the PGrens are terrible units to 1v1 riflemen because the rifles are much better up close and once they close in, decimate the PGs. However, add equivalent numbers to each side and the PGs start to win once they reach a certain point because they kill so many of the rifles as they charge, and then proceed to win in cc because of the numbers difference.
KCH are assault rifle troops compared to grens who are long range and guards are long range compared to short range SMG strelky. The fact is, that guards are cheap enough and have so many uses, that they completely phase out strelky in the late game. Guards need to play a role more similar to the KCH in creating breakthroughs rather than blobbing up as a mainline infantry.
