The result was the name "Jeutrémie", which combines the words Jeu (game) and trémie (hopper). Technically, it's the wrong kind of hopper - this is the giant funnel-like structure that you use to load up exceptionally heavy cargo (e.g. cement, ore) - but I suppose my the analogy to my MMO habit holds regardless. In any case, it sounds vaguely namelike and it has a pun on the theme I wanted, so I'm happy with it.
I understand the desire to have the legacy unlock - it also came with a bind-to-legacy token for a free weapon for my next alt to hit the teens - come as a special reward. However, there was a side effect to this plan - players cannot earn exp for their legacy until it is unlocked. The final quest in Chapter One rates at level 31, but I ended up pushing the envelope and clearing through it at level 28/29 (dinged midway through the instance, and a good thing since the final bosses were 32 elite and time-consuming).
I suppose the wait paid off in the end. I had a lot of fun pushing the envelope to get through those last few missions "early" (delaying the Tatooine bonus series and most of the non-story content on Alderaan until I could earn legacy exp for them). As a tank-spec trooper with a healing companion, I can get through a lot, and that level of challenge often isn't found in the solo game of an MMO anymore. Looking ahead, I see some tough choices on what classes to play next based on juicy perks to unlock for my legacy. From Bioware's perspective, that's a win/win, and I guess it is for me as well.
