Coh is based on RNG +100% chance to score a hit at max range is goes against the games design and is simply not necessary.
Else one has to lower penetration more or the unit will again be spammed.
Penetration IS lowered together with accuracy buff.
You still have RNG, even against ost P4 now, just not a string of RNG checks.
Also, blitz lowers target size.
And no, CoH is NOT based on RNG, its based on PREDICTABLE RNG, vast majority of the time you can predict which unit will win, unless some really bad luck is involved.
Only pure RNG weapons in the whole game are indirect fire weapons.
Also, there is plenty of weapons who have 100% hit chance already, AT weapons included and somehow they aren't a problem.
Underused supplemental unit won't suddenly change that, especially since the reason it was spammed was -NOT- its AT performance(AT buffs simply made it relevant against anything), but efficient barrage when multiple units performed it and muni cost effectively killed that.
