I've played a 2 hour game on LT, they aren't always that short and sweet, but it's good with the number of expo's that it has, because that way you actually have to fight for expo's, otherwise more people would tend to expo up and go.. Carriers.. *vommits* or.. BCs!!
Never complain about Siege Tanks.. The way StarCraft is balances them out, every race has a way of easily destroying tanks, even when they are up on the cliff. Cliff's provide advantages to all races for their drops. High Templar/Cannon drop for Protoss, Defiler/Lurker drop for Zerg, Tank/Ghost drop for Terran. No defense is unbreakable.
I think if Big Game Lost Temple became popular I would have to quit life..
The problem with Blizzard coming out with new maps is that no matter what they come out with people are gonna play the same thing (BGH + Fastest.. Oh how I hate!). Here's the coolest idea for a Blizzard update, make it so when there are 7 human players and 1 computer player in a melee game the computer becomes invicible.
The only changes required to make LT 'perfect' would be to fix 9:00's screwed over expos from the cliff, 3:00's Siege Tank blast on the gas, and 9:00's Siege Tank blast from below. Then that map would be a perfect example of a good map, then they have to force people to play other maps they make.
Maybe SEN should have a night when we play pure melee maps that people made.
