I wouldn't call this a stamina combo. Only one part in it has any use in stamina. Also when I tried Orso it did quite bad for stamina. Another thing is that you need to post results or this will definatly be closed.
He's not being a killjoy, he's stating a fact. If you're going to post a combo, you should also post tests related to the combo to show how well it runs, such as win-rate against top tier or high tier combos. If you're going to call him a killjoy, then you're only admitting that you're not willing to listen to others.
Don't post a combo that's based on your own opinion.
