Oh but the alternative routes give you "Ohh cool you can get there aswell." In versus we have taken that route just because it'll always give you some pipebombs and molotows, also when you get out of there the infected doesn't have that many places to ambush your from. People often go past it because they think the usual way is faster, yet it's more predictable. It also gives another interesting exploration question, do you risk losing few health points of the more dangrous route to try your luck if the more dangerous route has medkits/pipebombs/molotows/pills.
Also, in the school, the nurses office is situated right above where I plan the first saferoom to be. You bad enough dude to risk your life for some pills?
Maybe not in versus, but in coop it would be sure thing.
