Lately I've been thinking for that it would be fun to use really underused units and/or build for the sake of beeing annoying. Or well not exactly annoying but cant really find a better word for it. If I recall correctly NewbieMcNasty did this with vultures waaay back when they were underused and considered a newbie units.
My plan is to select a suitable unit or possibly a unit combo that is weird bordering silly, practice it quite a lot and tweak it a bit until I become really good at it. It doesent really have to be even remotely viable since you'll get 50% wins anyway, I'll be doing it since it should be a interesting challange.
So to sum it up, I'd like to get some suggestions on what I should go for. Also if you have done something like this I'd like to hear it.
