The balance team claims that "popular sentiment" says T4 is not accessible enough so the solution is the make it more accessible. I highly doubt that is the sentiment.
Not accessible is very strange considering it's already very cheap to get T4 when you have T3/BP2 as Ostheer.
The problem with Ost T4 is that none of the units are suited for 1v1. In 2v2 the Panzerwerfer is good, Brummbär and Panther are mediocre and overshadowed by Tiger. Ost T4 is meta and strong in 3v3 and 4v4.
