I LITERALLY FOUGHT SOMEONE OFF LAST NIGHT!! Can you not read or can you just not comprehend? Not everyone has a 3k dragonite, in fact almost nobody in my area does. The person I was fighting may have had a weaker pokemon, but whatever they were using could not kill my poliwag and my friend's snorlax before the poliwag was killed, AND he was likely using a hyper potion every time.

I'm sure that you can fight off a bubbler with a 3k dragonite vs the bubbler/Snorlax. Hell you might even be able to take on 2 Snorlax's, but I doubt it. You're only factoring in ONE scenario when there are MILLIONS of different combinations on attackers and defenders. Your argument is so asinine, clueless and closed-minded that it's literally not worth talking to you anymore.

The bottom line is that some attackers will be able to fight off a bubbler and multiple tanks, and some will not. The more tanks you add after the bubbler, the fewer possible attackers will be able to take it down. If I'm defending a gym with my cp18 poliwag and 3 2k snorlax's behind me, you will 100% NOT be able to take that gym from me without another person attacking with you. That is a FACT.
