I suppose it's difficult to debate whether a game has all its balances in check when you can end up with so many stalemates.
10 minutes until a game can achieve balance.
Vehicle lockdown from the enemy team can always be countered if players come together with infantry to decimate light/heavy amour, it's just rare for this to happen.
All of these, except for the last one.
Could EMPs just detonate remote C4s instead? Useful so long as your team, vehicles and/or buildings aren't within proximity.
It is also rare for enemy remote C4s to still await detonation when defending units get close by.
