O boy a one trick pony in Diamond! Wait no he didn't get his champion or his role!

That Diamond one trick player skill level just drop from Diamond >>Silver-gold. Problem I hate in rank is one trick that if they don't get their role or champion they have the skills of a Silver>Gold player. Worst case scenario is that they would try some stupid off meta move like Kass Support or Kass top which is sound okay but is easy to counter when players who a diamond have multiple champion tier list in the lane.

People can say one trick are skilled but they are a problem if they don't have that specific champion or get their lane, this happens a lot when in Diamond you get autofill quite a lot which is a extreme problem because it's like having a gold skilled player playing with diamond. I always recommend 2-3 champion in your main lane and 2nd lane choice not all in 1 champion to play rank.
