Sorry, but T70 is a tank.
Yes, which means its impervious to small arms, unlike all other light vehicles.
Which is exactly why, at that timing, the Shrek needs to be more practically effective vs it.
This is currently not the case, due to the indirect result of T70 being able to move in and out of range or LoS while the Shreks cant get even a single shot off, while bleeding generally 1 PGren per T70 hit.
Currentky it can just play cat and mouse with them, as the cat. Whereas at their enormous expense, its the Shreks that should be the cat, or atleast a mouse with a very big stick.
T70s general AI efficacy is fine. But when Ost invests 120 Muni on a 360MP unit, it needs to fuck off entirely.
Does it currently? No. It can just bleed them from range and moving in and out of LoS while the Shreks bug out and cant get a single shot off.
Perhaps the solution is a shorter aim time on Shreks. This can be offset by increasing the reload timer.
To the result that Shreks can atleast get an initial salvo off, while then taking longer to fire the second.
In this way the aim time reduction, coupled with a longer reload, would remain largely the same net result in more protracted engagements vs Sovs later heavier armor as well as in infantry engagements throughout.
