Unfortunately, for Dragonite to be able to 2HKO the metagame, it can run what? 4 Speed EVs? It'll need life orb as well. Dragonite's base speed just plain isn't good enough for a wallbreaker without investment. You're also going to lose Multiscale after one attack. This means that basically everybody is gonna outspeed you and smack you with and ice move or something.
You still don't get it right?
Dragonite doesn't need speed for 2 reasons:
1.He has Multiscale to take most attacks with ease and then proceed to kill stuff.
2.He has strong priority!
Try to find some faster pokes that are not 2hkoed by Dragonite with one move(Thunder,Aqua Tail and Hurricane) and Extremespeed.
While I support the use of Rain Abuser DNite, don't be dumb and go on to say how the set can 2HKO the entire metagame.
1) It is slow as hell, so half the metagame can either revenge kill or survive the first hit and KO it.
2) Many Steel types I believe are certainly not 2HKO-ed by the set (eg. Specially Defensive Bronzong)
Rain Abuser DNite is an excellent Wallbreaker, however it's not exactly a "beast" persay, as I feel it's greatest merit is in the surprise factor.
I said almost the entire metagame!
So come on and try to find some pokes that are not 2hkoed by Dragonite.
And when i mean 2hkoed i mean that if they are slower than it then they must take 2 attacks,1 when they switch in and 1 before they attack,and if they are faster they must be able to take the first attack on the switch in and the extremespeed after.
Also the standart 252/80 hp/def Bronzong is 2hkoed 95,6% of the time by Aqua Tail in rain with SR and Lefties calculated.
Specially defensive is even worse as it is 2hkoed 100% of the time in the same situation.
So pls tell me some counters!!!
Finally revenge killing doesn't matter so much 'cause it is not supposed to be fast.
Wallbreakers must not necessarily be fast.Their main goal is to break walls!
And that is what this set does!!!
The set i am talking about is this one 'cause i am not sure you for which set you are talking about...
Dragonite with Life Orb max Atc,S.atk,quiet and Thunder,Aqua Tail,Hurricane,ES
