There are guilds ranging from method to not being able to get normal clear till the next raids. If you play with people in your mindset, you will have fun and that is what matters most. So no need to defend your guild.

About the kiting: The next add you are kiting towards should get a banish so it won't take damage and die before you reach it. Killing adds by cleave gets worse every ID, but as long as the boss dies, the tactic is good enough for your group.
