Well when those dragons are Salamence and Dragonite and Garchomp, well...you see where I'm coming from(the former being more popular). The only reason I say it's too much is because I want to avoid another Pokemon like mence come into competitive play. It seems to have taken Garchomp's place rather neatly when it comes to complete sweep and little counters unless it's Cursepert or Umbreon but that's getting a bit off-topic.
Just wanted to explain myself. :( Of course, I guess I wouldn't mind another pokemon like Salamence, but it's just...the power that it has tells me that there are a bit too many dragon types. D:
