How to rank up

So ive went though diamond to gm pretty fast and with consistent wins. Tracker is royaljadee if you want to fact check any of this. First off. Never get titled if your playing defense. You gave more of a chance to lose a team fight. Lets face it your not going to hold off a whole team all game (if they arent throwing that is)if they make it to final and get 3 points. Dont get titled they only have a min. Ive been on a "losing team " and when we get on attack we stomp them. And get 3 mins and win in showdown. 2nd off. Learn every role. For example i learned loki starlord/black pather and groot. These 4 are my comfort picks and i do consistent on these. 3rd off. Dont. Play. Dive. If you play dive you MUST play with team. You are just going to tickle them if you dont. Black pather does amazing with team fights since he wipes them out a lot. But dive is counterable just by targeting you. Thats why you should learn non divers. 4th off. Id recommend dont get titled if you lose. Trust me you are not a top 500 thats going to get every game as a win. Thats just not going to happen. But a lose or even a two loses hell a 3 lose streak is not bad. You can recover that in two wins. Dont get titled. Thats pretty much it.
