I was there today, it's not great but it's not that bad either. There are definitely seats for sale that are worse than others with slight obstruction issues.
Compared to the true partial view seats though, it's wild. I went to the upper bowl in one of the sections not for sale. I was 4 rows from the railing and you couldn't see the entire near side faceoff circle or goal
Also just to add fuel to the fire/clear things up. As of right now there are no plans for a new arena. Smith will be upgrading Delta over the next 3ish year (I think?) to renovate/fix sightlines. A lot of people missed that there will be no new arena as of right now in the chaos of the move.
That could change with the 2034 olympic bid, but unless Smith can magically find land downtown for a new arena, it aint happening and they aren't moving the team out of downtown
