The original Dust is immensely popular amongst people who just enjoy pubbing as well as the occasional “competitive” player. It is a great map that forces a side to cooperate amongst themselves in order to achieve a win.
As far as Season goes, I think it is fine if the map is a bit large. On Dust2 a player cannot go to one site, find out it isn’t there, and then get to the other within time. Most maps are that way, a few you are able to and even some techniques on D2, etc allow a player to get to a site as quickly as possible and is able to defuse as well. As Liam said, it doesn’t hurt to try.
