IWD says that if you want to climb you have to play what is meta. Currently Hash is climbing in large part because several fighters are actually in good spots including Jax currently.
IWD seems to have the mentality of winning is all that matters while Hash seems to want the game to be more enjoyable again. Yes Hash has played tanks before but he clearly does not like playing Maokai, Malphite or Naut all that often.
Most of what Hash says could be summed up in these 2 points.
- top lane isn't important enough in the game currently
- the game just isn't as fun as it use to be.
Both are subjective but just reading the boards it is clear that a sizable part of the player base can agree on the not as fun as it use to be part being at least somewhat true.
He doesn't want to play tanks because tanks are generally not as enjoyable to play as fighters in his view (only tank I really enjoy playing is Shen and he has a fair amount of fighter aspects to him). Hash wants fighters to be more important and for tanks to not be effectively less enjoyable to play fighters with often times better engage and CC while also having comparable damage.
