That big flying yellow tracer isn't good enough to spot the enemy tank?
Not to mention it's always daytime in the MA, making muzzle flashes have a really small effect. Although night time... That would be a sight to behold, 20+ tanks duking it out in the dark.
It'd be nice, but I'd rather we have better graphics effects that are more commonly seen, fires, smoke, clouds, vapor trails, maybe dust behind tanks driving on sand even.
