Seriously though, how awesome would be our own personal Commander Shepard in DA (even if I am *mostly* joking). 
We could even get him/her in 3 varieties:
1. Biotic (mage) Shepard.
- in addition to the standard flavour of a biotic's ability I suggest the addition of the following skill:
"Shadow broker" - this skill summons your favourite companion on the battlefield to aid you in your fight. Upgrade: "Reach and flexibility" - you get the option to make out with said companion on the battlefield both earning the admiration of that ballsy act from your teammates (+10% to crit chance for everyone) and shattering the resolve of your enemies (100% weaken chance for 10 seconds) as they lose armor while contemplating their sad loveless lives.
2. Infiltrator (rogue) Shepard.
Special skill: "I Should Go" - Shepard tells the enemies that... she should be going, going into stealth and leaving them pondering their poor life choices. Upgrade: "Paragon persuasion" - by the sheer power of your words, you change the mind of your enemies with a cliche line, leaving them confused and fighting each other for 10 seconds.
3. Soldier (warrior) Shepard.
Special skill: "I've had enough of your snide insinuations." - nothing special to this one. You slap the enemy hard, knocking them down. Upgrade: "I've had enough of your disingenuous assertions" - your slaps are now so mighty that you are now all the talk on the enemies twitter accounts. This upgrade give +100% damage against humanoid enemies, because they are easily hurt you insensitive brute. Additionally, they get +50% damage to their bills for psychological care.
I also suggest the addition of a playable Reaper.
Special skill: "I am Sovereign" - you start a deep conversation about the cycle of life, the futility of resistance and also call the enemies' mothers fat. This skill puts all the enemies around to sleep immediately but when they wake up they are slightly mad at you (+10% more dmg against you).
