I'm not saying they're the only useless faction, but they did have a use and now they don't. Not only that, but Tuskens are 3 toons and actually have an omega battle that they can be used in (I think jawas do too, actually). There are lots of useless toons from meaningful factions (Lobot-Various Rebel Events, Mob Enforcer-CH/DH), and there are other useless factions that have useful toons (Separatists-Asajj/B2/Dooku), but a useless faction made up entirely of useless toons? That's just terrible.
Look, I run 2 alternate accounts that don't have jawas or crit damage mods yet (I was farming them, but that's fine, I'm happy to stop) so this change actually benefits me. I'm not bitter or anything, I just don't get why they would want to have any more useless factions than they already do. I would think the goal would be to give people more reason to use all the things you've built into the game, not less.
