You simply can't have one class of infantry killing suit that splits its opponents into two classes, one that can't touch it, and the other that can, but now at a big disadvantage to defending itself against other infantry.

That split magnifies its advantage over enemy infantry by splitting it into two groups. If you chose a weapon capable of fighting the tank you are still vulnerable to the tank but now you make yourself even more vulnerable to other infantry.

The tank suit doesn't have to make any choice. It is equally effective at killing AV infantry as it is killing AI infantry.

You don't really give up your tank bashing ability with blasters. You can still fight tanks as well as infantry. Plenty of people manage it as the blaster tank can take advantage of its turret speed to dance around a rail tank and stay away from its main gun.

Tanks are just meat inside a small bag inside another bag.

The problem is the blaster tank is great at everything while its main opponent is crippled against it.

The problem is demonstrated by the fact that we have a vehicle cap and without it we would get Ambush matches with 100% tanks on at least one side. When you have to artificially limit a role you know it's OP.

It doesn't matter if another tank can counter you or not, that question is irrelevant. Lets just say I concede your point and rail tanks are your natural predator that you can never escape.

Your role then is 100% AI. You compete directly with infantry for infantry kills. Therefore your fitting must be balanced with any other person playing that role. That means you are just as vulnerable one-on-one with any other infantry unit. No fair saying that only some small percentage of infantry can hurt you when you can hurt them all. No fair saying that if they can hurt you they can't hurt other infantry.

Forget for a moment the outward aspects of your suit and concentrate on the role. Design the balance with the thought that your opponent gets to chose which role you play and which role he plays after you make your choices. If you make one all powerful he will chose that and give you the weak one. Do that honestly and you will see that tanks can't be AI focused and still remain recognizable as tanks.

Outward appearance aside, your blaster tank is playing the part of a dropsuit. It shares the same game role of infantry slayer as any other dropsuit. The role is the relevant factor here, not the shape.

When someone chooses to shoot others in the face they have the option of many suits. Each has different strengths and weaknesses, but all are somewhat balanced against each other such that there is no clear winner. You can go heavy, Assault, or Scout depending on your play style.

Or you can go blaster tank. It fills the same role.

If you go that route you get a fitting with far more eHP, DPS, and speed than any other option. It is immune to the majority of your opponent's weapons. It's so superior that there is no reason not to choose it if you want to win the fight.

There is a reason Ambush is a tank fest, it's the clear choice. So yeah, keep it the same and we will get DUST WoT.

If AI tanks are so useless, then why all the complaints? If they are a non factor then nobody would miss them.

Of course some maps render them less than useful, that's not the point. The tragedy is they don't have a unique role of their own. They compete directly with infantry and are either far superior or they can't participate at all.
