PGI knew what they were doing when they raised Clan Decks back from 240T to 255T : They were trying to make Clan Decks more attractive to inexperienced new MWO players, because they're not.
But no matter how totally clueless a new player is when joining MWO : Odds are he can still read what the top page of any Solaris Leaderboard Division looks like, and even a 400T Clan Deck made of four underperforming 100T Clan mechs isn't going to change that

You can drop Clan Decks straight down to 230T... But that would be even more clueless new IS mechs for Clan players to shoot at, and even more Ghost Drops for the excess amount of IS players to queue for.
