I want to say about kingdra.
Dragon scale quest was hard. And kingdra was very good so i didnt make metal coat. Because i love kingdra too much. When i see "johto will come" i made seadra 90 first. We waited too much. And in anime kingdra can use hydropump. Please change kingdra. May be , be hydropump less damage or delete whirlpool and we can add tm hydropump.
Kingdra is still pretty strong, first of all it can learn hydropump by TM already, also, whirlpool damage is pretty strong.
My kingdra 112 dmg from whirlpool - 2x,2,5k, and same with hydropump (agaisnt charizard), it gives 10k damage with 2 skills, you just need TM, but even without hydropump its pretty good (yawn please, its awesome too), so no, any change isn't Neccesary.
