...if LZ's ain't get blocked, then, someone must be there 24/7 to monitor, while the attacker, can sleep, wake up, drink his coffee, then try attack.. Success ? Cool - Fail ? well, lets go do our shopping, we try again later , and so on.
i also believe it is a shame that GvG didn't got an update, especially with the rediculus low HQ defence bonuses considering it was developed before the 1000%s and 2000%s attack/defence boosts, even before Orangery comes out, which works impo broken in CE, ignoring Tanks' Reactive Armor, with the result double or even single shoting them :-(
as a player, i feel the same like kool on this.
as a proffesional player i'm sure there is no concern. when the security access is on purpose low, someone is keeping the doors open for his reasons.
