Dragonite's 20 lower base speed is everything. Fairly self explanatory, there are MANY pokemon in the range from 80-100, and if Salamence can outspeed them, he is going to be superior. As a bulky or agility sweeper Dragonite does better, however as a pure offensive type pokemon, Salamence gets the job done. Also Intimidate means that he can come in on more occasions and Dragon Dance up, oustpeeding basically anything if they are +spe nature. Only revenge killable by CS Jirachi [depends on nature + EVs], CS Starmie, and CS Timid Gengar, and other priority pokemon.
Cool,except....I didn't refer to speed once. My whole post was about the offensive power of the 2 dragons and how that Dragonite is being seen as far weaker in terms of those 2 stats. Feel free to re-read my post.
If you want to try to switch in with a salamence when stealth rock is up, intimidate or no intimidate...it isn't taking another hit. e.g. Scarf Heatran 2hkos with rocks up so eat your heart out Mence. Plenty of things can do this to Mence.
The DD set is revenge killable by anything that can A)survive a hit (far more than YOU apparently think, as there is a thing called investing in defences) B)hard enough hitting priority C) Base 100+ scarfer.
If you actually team build effectively, then you wouldn't allow DDMence much room to set up. (ONCE AGAIN DOWN TO THE PLAYER...)
Mixmence is really easy to revenge seeing as just about any scarfer outspeeds it and there are quite a few pokemon who just naturally outspeed it.
Its all very well saying 'Salamence can come in alot and set up' but show me some things it is setting up on (ESPECIALLY that Dragonite can't). Lucario? No.....Gyarados? Usually no...Heatran?No.... If a Heatran is out and it wants you to not set up..you won't set up (we are saying Heatran has explosion, roar or a super effective move) because while you set up you will die. So really, it is down to the PLAYERS.
Dragonite gets the wallbreaker job done equally as well, and only does the offensive DD version worse because scarf Rotom ( a couple other scarfers too?)outspeeds it and it can't TIE (note:tie isn't a 100% chance) with base +1 base 100s. Dragonite is completely capable of filling Salamences' shoes should it be banned. To sum up, 'Salamence gets the offensive job done' can be said about Dragonite too. Anyway, Dragonite can DD up easier because it can run bulkier DD sets which it usually does. If the opponent wants to switch out in an attempt to counter Salamence, where is your Intimidate there. Dragonite has staying power.
I get the feeling alot of people are looking at this whole Dragonite thing on paper far too much, when in reality there is little that Salamence can do that Dragonite can't, other than look like a blue/green pancake. Actually, I get the feeling alot of the anti-Salamencers in the thread aren't using personal experience to make their judgements. Its like 'Salamence has awesome stats so it is uber coz it can run 2 good sets too!', seriously, when you break their arguments down, that is what they are.
