14 attack IV Raikou
Answers
I don't understand people's obsession with break points. Do you know how much precious stardust and candy you have to waste to go from 6 damage to 7? In my opinion, definitely not worth it. I've got only 1 Dragonite slightly above level 30. I will never take another Pokemon above level 30 again. It'a a waste, IMO.
Correction: I also have a Blissey well above 30, but that's because I live in a high turnover city and needed something powerful to stay in gyms to get my coins.
But that is exactly the point. Checking breakpoints is a way to help decide whether or not powering above 30 is going to be worth the stardust investment.
If the last breakpoint against a raid boss is at level 32, then powering above that is only giving you a tiny bit more HP.
If you really like a certain pokemon and decide to power it to level 35 just because, but there is another breakpoint at level 35.5 then you are missing out.
