League is infinite cycle of metas...
Back in season 1/2 there were no metas(which is why players favourite seasons are those two bcs you could play whatever you wanted and still carry if you are good).Then in season 3/4/5 assasin/adc meta came and,while it was their meta,you could still shut them down with defensive items/way you play(ie.vs rengar you never go alone and always stick with your team and buy randuins omen for example).But now,since season 6/7 its been tank meta(and IMO the most boring meta),games are finished at around 20 mins,very snowbally and extremly hard to get back when behind.You cant outdamage tanks(which is BS) and they can easily one shot you+need your entire team to focus him just to bring him down.But dont worry guys,there will be adc/assasin meta again,where games will be more fun,wont end at 20 mins and you could come back when behind much easier.[slayer-pantheon-thumbs]
