Maybe this is going to be a very unpopular opinion, BUT... With the fresh start with the Early Access launch, no even a single engineer had the Tandem and that did my experience with and against vehicles a much more enjoyable one.
All the vehicles had been more useful now that most transport vehicles cannot be destroyed with one single hit and heavy ones can play an assault rol, making the matches more dynamic.
Tandems make supporting infantry with vehicles in a frontal assault being a high risk/low reward.
I wrote a essay but the character limit don't allow me to post it, so I have a more in detail .txt.
