And then how should infantry deal with vehicles? Vehicles in general will always have better range, better firepower and have enough speed to get out of the shorter infantry range and repair up. Most of the c4ring is done when tanks are farming infantry, and its the only tool infantry has that has a good chance of success for a kill without the target killing you or getting out of range. As I've remarked before that if C4's AV ability gets nerfed infantry needs something in return so they have the capacity to effectively engage vehicles without needing a dozen lives and a squad of firepower to do it. Nanites destroying nanites has always been my favorite. Such weapons dont even need to be high-powered weapons of vehicle destruction. With the addition of weapons that debuff the target either temporarily or untill sufficient repairs are made you could give infantry the time and range it needs to finish vehicles off without them just driving away. Other tools could have extremely high firepower but you buy it like a MAX suit, once bought you lose it on death. This gives a higher risk/reward for using such a weapon against vehicles but does give infantry the bite they need. I always loved the idea of making the relationship between vehicles a much closer one so we can have actual combined arms and remove many of the walls segregating infantry and vehicles. To make vehicles still feel powerful they could be filled with tools, gadgets and weapons to deal with infantry in return. Co-ax guns, mortar racks to flush infantry out of cover, the gunner receiving abilities like a directional shield or scan equipment to make its role more enjoyable etc. Too high a TTK is what breaks the balance between infantry and tanks, so if you make it easier and shorter for infantry to deal with vehicles you have to make vehicles feel like a swiss army knife with lots of tools to deal with said infantry... if you can get them before they get you. The option to buy extremely cheap or even costless variants of current vehicles should also help the game tremendously. A vehicle oriented player should always have the option to use a vehicle and never feel restrained. But just like infantry these vehicles just wouldnt be as good and would rely on utilities (that are persistant through death like C4 is) to be fully effective against resource costing vehicles.
