BF3 Vet here.

The problem with Vehicles right now (From an infantry standpoint) is our inability to DEFEND ourselves.

In BF3, you could attack infantry easily, but you still had to watch out for Engineers. SMAW's and RPG's would tear you to SHREDS if you stuck around with competent AV. (I used to love tag-teaming tanks with a buddy. We could distract him with RPG's and have another dude hit the sweet spot and disable. Once disabled, he was as good as dead. Smart Tankers would immediately get range and let the gunner do the work. Idiots would try to splash us with the main gun.)

Not the same here. I've seen tanks eat rounds all day, and due to Swarms requiring lock, you really only get 1-2 volleys off before he pins you down and stops you from firing another shot.

Now this in itself isn't really a problem. Just use more than one AV. Same in Battlefield.

HOWEVER, you have to spec into AV here. You have to have the Fit already made and ready to respond. In BF3, EVERYONE had access to an Engineer with all the tools ready. MLT Swarms are a joke in comparison. MLT tanks are FAR too powerful for their comparative AV.

Tanks and Infantry need a HEALTHY relationship in order to co-exist. Tanks need to be viable forms of both Anti-Infantry and Anti-Vehicle, but they cannot dominate both aspects. It creates inbalances.

Same for Infantry. We do not need to lord over tanks like we did in the past. 2 Swarmers shouldn't lock down the whole map, the same way that a Blaster and a Rail shouldn't prevent most infantry from being able to even leave the city.
