I know you distrust any build that isn't used in a competitive tournament
Nice strawman, but I have my own builds for my champs. I don't even follow guides. It would mean ruination for me mid in our ranked games if I just blindly copied builds from teams that have those builds because they correspond to a playstyle and an overall strategy that our team couldn't copy even if they tried.
many people do is pretend they're 2k+ ELO players when trying to determine what is viable and right for them to do.
My mains in ranked are Galio, Morgana, Annie, Cassiopeia, Ziggs and Brand, and we're testing Veigar at the minute as a counterpick. Only one of these is used consistently by tournament teams, the others are niche or used less often.
We use Galio because most people aren't that used to playing against him, and I do well with him against my consistant bane LeBlanc (I'm so shit at playing against him). Playing Galio also means we can "trick" people into picking Kassadin.
We play Morgana to enforce a "neutral" lane - that is, don't lose it, just win it in farm and gank a bunch.
We play Brand and Annie for our team-fight comps (though we're moving away from this strategy).
We play Cassiopeia and Ziggs for lane dominance.
Veigar we're testing because we frequently seem to go into late-game, amongst other things.
Neither of these strategies except the Cassiopeia one is very popular on high ELOs, though Galio is used sometimes as a counterpick and Morgana is sometimes used too.
That's why I always got Mejai on Morgana when we played together. (I could rely on my opponents making enough mistakes that I could fill it).
The opponents we played back then are complete scrubs compared to a decent ranked team on EUNE. So were we. Mejai's is win-more anyway, the game's we won with you having Mejai's we would have won without Mejai's too.
Also, Berekan reads Spanish, not Danish
Alas, Piet Hein doesn't translate well, and it was the most fitting quote for the situation. Indeed with the above you seemed to have miss the point of the quote. You have fun with your Twitch, seriously. I'm not saying OMG SCRUB DON'T PLAY TWITCH. I'm making a case that he's a bad pick if you want to win in a "serious" game (i.e. ranked). This goes to an extreme degree for solo queue (because your team mates probably won't fit their playstyle to him) but it also goes for 5v5 on any decent ELO because people there will know how to play against him.
He is easy to counter, utter crap in team fights, his ganks are not that threatening and if he doesn't get fed he's
completely useless. Playing Twitch is a complete gamble on your opponent's lack of skills. If he doesn't do very well, your team is fucked. And this is point, isn't it?:
Other junglers with as good level 2 ganks, as good a presence in the jungle and faster clear-times will be an asset to the team even when they get a bad early game. Twitch on the other hand becomes a colossal ball and chain.
