So I already talked about what is new to Late War in terms of books/pdfs/digitals. Now it is time for some more guesses of what would be the popular builds for the upcoming ETC.
This one is not so easy I have to admit. I think I cannot nominate (although I might try later on) specific briefings, as there is probably over 200 to go through, but some groups can already be identified.
Always Defend Tanks - this one is easy. Since the introduction of Bridge @ Remagen, there was a discussion if Always Defend heavy tanks are the new black. Well, honestly - I am not 100% convinced they are, but now they are at least something you have to consider each time you build your list. For ETC purposes, my opinion is that they can fit in just perfectly. Being able to defend more often, yields a higher win probability as shown by this year's ETC top 4 teams results of defensive battles, where the defenders won 58% of such games.
