BtA. Always BtA. If BtC is ever suggested for *anything*, the person should be slapped with a wet noodle. BtC needs to Go Away. Period, end of discussion. If I get something on character A, I should be able to give it to character B who can actually use it. They're both MY characters. They're both ME. There is no reason why just because I got lucky on character A, character B should suffer.
Additionally, Comms of Valor should drop in chests, like Tokens. Ideally, you'd rename Tokens of the Twelve back to Epic Dungeon Tokens and rename the Comms Epic Dungeon Tokens and combine the two, or rename Tokens of the Twelve to Comms of Valor and combine the two, or have some way to convert between the two. But Comms should drop in the end chests. You should not be required to run Sagas to get them. That makes Sagas no longer a "bonus", that makes Sagas a requirement. Keep them in the Saga rewards, sure. But have them drop in the chests as well. Let me have the actual *choice* of end rewards. Let me take the renown for my, basically, two-person guild. Let me take the Upgrade Tome of Actually Useful Skill if I want. Let me take the XP to give an off-ED a booster shot. Let me have the choice.
