TBH, I think commander mode should be canned. It was OK in BF4, although a pain if the other team had one and you didn't, but in BFHL, it became completely overpowered. Wall hacks for your team but not the enemy just annoys people playing the game properly.
Could have been some interesting ways to implement spotting mechanics, spotter planes or basket balloons with lookouts on it. Just sort of surprised there hasn't been a big deal made out of it not being in this, i think it was BF3 originally wasn't going to have it and the ea forums went ballistic.
Only ever played the beta of hardline, 30 mins of that was enough for me to say nope.
