Personally, I think Lend Lease commander is probably the most fun commander to play with at the moment. The DSHK machine gun is alright, but I mostly use it in combination with T1. Shermans are the fun part of this doctrine. I have no problem having 2+ Shermans mostly if I don't tech.
OKW needed the Ober nerf = Check
OKW needed the shrek nerf = Check
IG needed the buff = check
KT needed the iWin button nerf = check.
Now OKW can be somewhat competitive and not bat shit OP. OKW was abomination in team games, no wonder all the n00bs picked this army. Now the ELO has been adjusted just for this. LOL
I think automatches for new players is a huge problem. The problem is many new players get a game against AT or strong opponents and end up quiting with sour taste in their mouth.
