I strongly dislike the new LCS Varus build
Currently, LCS players seem to have an unhealthy fascination with the Muramana/Lethality Varus build.
Now, there were a few games when that build looking good - these were game in which Varus' poke was really valuable, against teams that had Jayce in top lane and a squishy jungler.
However, when the enemy team has a tank (dislike "supertank" as a word, too - those are just your regular tanks!) in the top lane, potentially a Rek'Sai or an Armor-building Lee Sin in the jungle, that build always fails to make a dent - as it essentially means that Varus can't make good use out of his W and the buff to his passive due to lacking the necessary AS.
