Is there a need for such a tournament?

it differs in structure from the vampire one

in what way?

I'm also a conservative

although in Heroes 4 I play as the Equilibrists
and in Heroes 5 I'm waiting for version 3.1, it seems the developers have either forgotten about it
or are preparing a pleasant surprise

p/s
it's just that you switch from one to another
and sometimes you are very surprised when access to your favorite skill is suddenly blocked ;)
