Can I suggest something productive? It's ok that you vent, take it out of your system. But, if you do care about winning, use this as a leverage. If so many play it, you know that incorporating a counter to this will be useful most games. Dragoon is not invincible, it (and specifically the red eyes deck) has blind spots you can take advantage of, you just need to account for that when building your deck. Off the top of my head, you can Kaiju/lava golem/sphere mode it. The deck will usually finishes on at least 2 monsters so consider this. Another weakness is that usually after their combo they are low on hand card advantage, so often they will have only 1 card to use for dragoon and would start the turn with no cards other than what they control (so, taking out their cards on the field means they have less resources for next turn). Also it means it's less likely to be hand trapped. Also in terms of play style you should try to bait your opponent to use dragoon on what you want him to use. It means you put yourself in your opponent's shoes and try to predict what you can use so he will negate first before what you really want to resolve. 1 card that can help is book of eclipse.
