Lol I'm sure there are ton of people not having done "enuff" research or "objective" enuff and started off by putting things together from scratch. Just copying doesn't guarantee results, you still have to play your team to see if that results was up to your told expectations, explore further, do duels and test and maybe tweak it as best you can. Most of the time, not having the right ninja for a famous already meta just means you got to improvise, collect and grind which are all part of the game.
I don't think the forum represents the majority views of what people are doing, merely that the ones who speak up and including veterans are ones that want to find information and it certainly is true that that knowledge can give you better insight if we want to decide what to spend coupons (gamble) on. That's exactly why there is so much fuss, because most don't know how effective our new ninjas gonna be base on hearsay until we test it our firsthand, and we are omitting the experienced players who already know exactly what meta work and what don't because I kept hearing there is a lot of those start over 2nd time players. *shrugs*
