Generally I'd agree but this is a tournament to figure out who the toughest contender for TheViper is. Liereyy has been widely considered clear #2 for a long time and is still considered #2 by many. Therefore you kind of need to invite him to give players the chance to "dethrone" him.
A tournament without him wouldn't have fit the purpose. Most people would have said "how can you ask 'who is #2' and not invite the #2?"
It wasn't a critique of Lierey being invited to this tourney. Just a general suggestion to sponsors for the future.
