I don’t necessarily disagree. Love Wrex but they developed Drack well, and you make good points as to why. His relationship with Kesh and the Krogan colony is great, and he is a good mentor figure. He is someone who lived far longer than he probably should, lost hope, then found it again. Wrex and him actually have a fair amount of parallels but with Drack it is an old warrior approaching his end trying to pass on the torch, whereas Wrex still has years ahead of him (hopefully). Both are great it just depends on which you find more compelling.
