Gen 2 new CP coments
After the gen2 CP update we noticed some very interesting pokemon.
Ampharos - Good Electric Pokemon to pair with Jolteon on attacking.
Espeon - new Psychic beast on attacking
Steelix - maybe a good defender due to Great defense and typing?
Scizor - great typing and attack stats, can be awesome with good moveset
Heracross - The hope for effective Snorlax countering depending on moveset
Kingdra - good to attacking due to typing, stats and moveset probably will be good
Donphan - great stats, can be the next Rhydon
Tyranitar - new dragonite, needless to say anything
But we got a problem because BLISSEY WILL BE DAMN BROKEN.
Imagine to fight a gym with 4 or 5 of this?? There's just no time for it. This pink ball will be the devil!

A short calculation tells, that without type-advantage, blessey could be killed by a same-sized-alakazam only using its quick attack in 55 seconds, whereas time limit is one minute afaik..
I think, taking charged attacks (or type-advantage - any strong fighters in GenII?) into account, others will be able to kill her too.
[Edit]
Heracross is Bug/Fighting with good attack-Value
[/Edit]
Another possibility would be to kill her with teamwork.
Yes, she would stop training. :-) This is ok, it is just a disadvantage for the team, that has put her as a defender.
At the moment, fighting moves are too weak. Only the slowest one, rock smash, deals more then 10 dps.
If niantic would fix at this point (as they did with water gun, which was much too strong in the beginning) even Machamp could become interesting. With the given three fighting quick attacks, even heracross would be weak.
Heracross cannot be effective counter to Snorlax because weakness to Psychic (Zen headbutt). Yeah sure Heracross can prolly kill him if you dodge every hit but that doesnt make him a counter. For countering a pokemon you need an advantage, if both pokemon hit each other super effectively, neither of them counters the other one.
Lick Snorlax is not a top tier defender anyway. Tyranitar will very likely be the first real counter to Snorlax because he resists both Zen headbutt and Hyperbeam/Body Slam.
Scizor and Steelix could be potentially good counters aswell, depending on final stats and moves. Heracross not gonna happen though.
Maybe, they just will not let blissey enter the game.
Or they find another way - maybe with only one pkm of the same type as a defender in each gym. One blissey can be beaten, and at the moment, gyms fall too fast anyway.
I don't expect them to adjust stats formula just because of one PKM. I expect them to adjust lapras according to the new formula too.
