My general climbing advice for plat players based on both streamers and e sports.
hard to find a coach who's helpful right now when the entire games going to be shaken up for about half a season even pro players are slow to learn and change. On a more serious note if you want to post replays on the forums people can give you some decent pointers while you get the position filled.
so your in plat that means you are pretty good with your champions most likely and cs count should be decent at that level
look at timing jungle camps and routes the enemy jungle is taking based on his cs also roams and lane swaps are pretty important here
and wave manipulation slow pushes before objectives can win you team fights and objectives when they go to clear the wave.
One thing i can think of that a lot of people do wrong is killing the enemy champion is not always the right approach if you can keep him in lane but afraid of the
all in you can starve his cs and most people don't like just eating the bullet and backing won't work on a smart opponent but should work on most people.
learn win conditions and abuse them this depends heavily on your comp and their comp so unfortunately with out posting a dictionary i can't give and advice here.
ps I know im unranked i play casually now days but i do study league constantly so my knowledge is pretty decent. Not applying for your coaching position but just wanted to help some bros out gl with your team if your in plat i think for sure you can climb with practice and study. [slayer-pantheon-thumbs]
