Lets say that this is whats going on. Your playing lost temple. You are protoss and your opponent is terran. The game starts off. None of you rush so nobdy is killed early. Now the terran player starts to wall off with tanks and turrents. What in your guy's opinion is the best way to destroy this threat. Im Thinking using arbiters to reacall into an area of the base that is undefended. Then work your way forward to the wall by using corasairs to desruption web. This is just one of many ways that you could break down a wall. What do you guys think?
