Yes I am serious about the part with the lack of brain.
I can say that about the whole world. 90% of the world-population are morons that are so stupid that I wonder why they do not forget to breathe. And I am not talking about education (Education got nothing to do with intelligence - in my humbleholy opinion. People these days simply are consumers. We got nearly no thinkers anymore. 9 of the remaining 10 percent are smart but I can't relate with them (or they not with me). And the last 1 percent is scattered around the world... once in a while I can find somebody to team up with.
And its up to you... are you one of those 90 percent? or one of those 9? Choose wisely!
And nope, I do not demand that you hardcore-roleplay. I also can take a little fun and some modern banners. If its bannerlike. Like the coffecup. Not medieval. Not roleplayish. But still a banner that looks alright. Oh and I once made (refined) a hello-kitty-banner for somebody. Okay, a strange taste maybe... but still bannerish and all right.
But having detailed Comics and stuff in there... floating sperms... a neoncoloured portrait of some youtube-queen... a country-flag? guys... seriously? If you put in stuff like that you can put in laserguns and lightsabers, tanks and motorcycles, too. Oh. And dont forget the magic. black magic and white magic (seriously, where are the healers/medics?), blue magic and grey magic... and elves and dwarves and hobbits and vampires and... I should stop here.
Yes, you can mixture armours... but you will be laughed at, if you are a samuraininjagladiatorpaladin. Like they laughed about you in the middle-ages when you mixed your armour up too strange...
So guys... stay calm (unlike me) and think about it. Just because others use shitbanners... why should you? Be a good example and not a moronic one.
To the country-flags there is a special reason why i cant tolerate it. We already have these whole "my country is the best!" - "dont talk shit, mine is!" - "stop bullshitting, your countries suck ass, mine is the greatest!" discussions everywhere. This is a game. Play in your fantasy. I do not care about your country here. I do not care about mine, either. Stop bringing racism and hate to this game. And thats what you do with your flag. Thats why I burned an american flag. and why I would burn a german, too. or a french. or a hispanic. or a [insert-your-country's-Name-here]-flag.
Start to think, people! Maybe it will hurt a bit, but thats only in the beginning. Soon it will feel great. Trust me. ;)
