Because 70% of the times allied infantry doesn't support the tank even if you clearly shout it in the chat or in voice chat, take Iwo Jima for example on the beach after the first point you have Shermans available to take the inland, Great! but when you spawn and you find the entire enemy team on the cliff around A with the high ground, plus the planes strafing, you can't support the assault alone with the tank even if you want, so you try and you try to ask for support of the team but guess what 10 snipers are cozy in the rear line, 2 are strafing with planes meanwhile tickets run out, after 10 minutes of useless wait to have infantry in and around your tank you try to spearhead and not to CAMP farming kill but hey it's basically useless since every lv 3. assault player could unleash a foking nuke at your tank so I guess It kinda makes sense to make TANKS FEELS LIKE ACTUAL TANKS
