That's the big issue with story pacing. The base game and each expansion (group) are largely self-contained while having to encompass ever more powerful characters. Our characters are Council Members, Generals, Crime Lords... known to each of the galactic leaders personally and yet for gaming purposes they do everything themselves. Our actions are supposed to have an impact, yet at the same time there needs to be a largely coherent common story line - which is easier to accomplish with the small cog in the machine than the galactic power mover. But yes, KotET/KotFE was an incredibly screw up. It would have been the perfect place to include the class story lines again. Instead of the Chosen Eight we experienced in the base game and got some call-backs to in the following expansions coming back unto the scene, they were all disappeared and replaced by the Chosen ONE (the Outlander). We became the single most powerful entity in the galaxy, but weren't allowed to make any meaningful decisions, because that would screw up the entire future expansions... Now imagine, if Bioware had either given us the ability to complete eight small mini campaigns, one per class, showing us what the other seven classes were up to during the Outlander's carbonite vacation or alternatively to liberate the also captured and frozen other seven from Arcann's control (bonus points of they had given the option to use our own alts as stand-ins). And once we as the Outlander hit Ossus, instead of just growing simply our own faction we had to invite and convince the Empire's Wrath, the Captain, the Barsen'thor, Cipher Nine etc. and their power base into our Eternal Alliance. Keeping the group together until the fall of Vaylin would have been easy, but each decision we made would have alienated some of the Eight. And it would have really felt like an alliance... doomed to fail in the end. Not a row of toys given out they had to take away deus ex machina because we were maneuvered into a corner story wise.

Make the class specific cosmetic options available to all characters (after finishing that story line?). I find it pretty annoying, that there's no way to get the inquisitor scars or trooper/warrior tattoos on other characters. Heck, there's not even the full line of cosmetic choices available at character creation, because where we get special class content (like inquisitor scars) we are locked out from the regular choices. Cyborg for each race, not just Humans.
