What Two Skills should Guderian Have?

Explosives is niche, but before the inspiring update, I was a proud believer in rumor and explosives. The new update though, well... Inspiring definitely takes the cake, and for f2p, I do recommend the inspiring rumor build. Inspiring plains are for p2w people or people with tons of gens already. Oh, and fun fact: I have done testing of inspiring v explosives to see which does more dmg. It's on the ET discord server, but basically, the dmg diff is around 20 or so. With all these points, I think explosives is less useful on tanks. I still believe in it on inf or arty, but for tanks, there's better options.
