I fought someone with that thing and it pissed me off so bad. He had Leftovers + Leech Seed + Protect + Spikes on the field. I could not kill it. I think protect was the most annoying thing about it though. Everytime I got some damage on him he'd recover and then use Protect. I seriously hate tanks. They make the battle last twice as long sometimes and usually have very few weaknesses. I'm not sure if I want to use one, because I don't want to piss people off as much as that guy made me angry. I might just try to have a Pokemon that can counter him.
