I think it is out right stupid that we keep comparing Charizard and Alteria (and gyarados, but it only seem to be used as a lame counter argument;
we cannot compare zard and alta, lets compare to zard you know the drill) when in reality
they are not that comparable we should focus on comparing them to the rest of the meta. A good argument for alteria to raise is not
It outclasses zard, and neither visa versa. Its not like we have to have one dd sweeper in S, one in A+ and one in A
Instead, i think we should speak out on how they fare against the rest of the meta, considder risk/reward factor of using it, what team support does it need, what does it set up on (the dd veriants) etc. Also, good potential coverage is not necessarily a huge plus, we are all aware that alteria can run fairy + ground + fire, which is insane coverage, but it does not help it if it in reality only can afford running 1 or 2 attacking moves, the same goes for zard.
well, that was my two cent on that topic, now for my actual nominations/opinions on the topic ^^
(S) --> A+
I think the change to ORAS have been a bit harsh to our first generation baby. While the general speedcreep does not effect it very much, its still the fastest OU dragon dancer, and it still fares decently against some common scarfers, there have been a couple of new megas whom makes it a little less viable (
+
) Mega sableye is the new face of stall, and gives the bulky wisp set a lot of competition, even enough to the point where that set would rarely be considdered on a stall team. Mega slowbro is just a really good check that will almost always beat any variant of charizard.
Charizard have also gotten a bit more competition as a dragon dance sweeper, thanks to gyarados arguably have gotten better with the new move tutors.
TL;DR Competition as a dragon dancer and outclassed as a wisper is enough to push it down.
(A) --> A+
With the new move tutor introduced in oras, gyarados have access to a lot better natural coverage in water/dark, which means he have more freedom in hes other moveslot, making him able to run a succesfull taunt set, something he wished he could in XY. This makes gyara a much better stall breaker, as it is able to get past sableye and skarmary. It also enables him to beat some of his former defensive counters, such as slowbro and power whip less ferrothorn.
The general speed creep is also a very little problem, as he can outrun beedrill and sceptile at plus 1, simply by opting for a jolly nature.
(A+) --> A-
With sabley being the face of stall, mews stallbreaking capabilities are essentially gone.
(A+) --> A
I think mega venusaur have gotten a lot of competition as a wall, especially on stall. It also fears the large amount of psychic types roaming around the ladder. It is still decent glue on offence and balance, i think A is fair.
