If you don't like it, go play chess. There is perfect balance and no critical damage. Do not go where you are not asked, the game is fine. Critical damage has been in this game for seven years. Let's delete them because you don't like them, let's further castrate the game.
If you do like RNG so much, go play slot machines. There is perfect balance and all is RNG coin flips. Do go where you are asked, the game is fine. RNG coin flips have been in this game forever. Let's not delete them because you like them, let's not further castrate the game.
These over exaggerations are utterly useless. What is the argument here?
Nobody playing this game is seriously debating to remove all RNG. You're trying to throw people into your premade "opinion baskets" by implying things they actually never said. With the same reason I could say you should go play slot machines because apparently you like RNG so much it should be the only reason that determines the outcome of a match (see the fake quote above).
Obviously this argument is bullshit.
The only question is: Is there enough influence the player(s) can take on the outcome of RNG to be in control of what happens?
Main gun crits are to a lesser extend controllable, yes. But the outcome can often be game deciding, especially if you just entered mid game and this is the first tank on the field. They are also not reliable. You are good to go 90% of the time, but 10% of the time it screws you (or your opponent) over. Which makes it also different from the "normal" RNG of accuracy and penetration rolls: These are always the same. Every player knows what his odds are in a certain situation. Hitting but not penning 10 times might happen, but these events are very low. Also these rolls are frequent enough to usually even things out over the course of a match. A main gun crit occurs once, maybe twice a match. They can barely even out at all.
