For those of you who are unaware,GAB and GRB have 2 completely different types of visual mechanics,due to the nature of the different modes.
In Arcade,tanks will have a marker on them stating the name,the approx. distance and the type of vehicle (which becomes more accurate the closer you are to said vehicle)
In Realistic, there are no markers like that.
Now, where’s the problem?the problem is that this marker mechanic is inherently linked to how vehicles in the game are visualised on your screen,and this is where the visibility stat comes into place
In short: the stat is gimped and needs a serious rebalance. The % of visibility of a tank does not represent its ability to be hidden to the enemy’s eyes,and most of the times tanks that technically have a high % are literally not rendered into your screen until they’re up close,and i noted that this effect is more present in Arcade than in Realistic.
Of course in Arcade it might happen that a tank is rendered at a distance but not its marker,and in that case you can shoot at it like it’s GRB,but i counted countless instances of tanks that straight up pop in front of you despite the conditions being against them (max level of Keen vision,clear sky and no obstacles and enemy visibility higher than 100%)
