So I have a E2 crew (my only USA crew) which I use for SP, and it has 6th sense / BIA / Repairs (60%)
However, I have decided to go up the E5 line, which is a heavy tank line.
Should I start with a completely new crew (0 skill), or should I retrain my E2 crew to the heavy line?
I'm stuck between being gimped if I have 0 skills on a T7 tank (T29) or being unable to farm credits efficiently (SP is my credit farming tank; I need the repairs at least).
Any input is much appreciated
