I think to help out people with your issue they should add some generic character templates (for example, Tiefling Rogue Urchin, Wood Elf Ranger Hermit) which would be somewhat predefined like the games you mentioned. Maybe modders will be able to do this at some point. Also a suggestion, whenever they add more companions, try to avoid playing with them in your party during EA if you want to play them as Origins.
For me, I prefer the full custom system we have now, it gives me more replay value because I can come up with hundreds of character concepts. I haven't played everything you mentioned but for the ME trilogy I played only once and for DA 1 and 2 I played each only twice. DA:I I never finished but it would have been the same. Since the characters were predefined, by that time I had seen it all and had no need to replay anything, although I enjoyed them. Bethesda games I come back to a lot because I have different character concepts to try, although I use alternate start mods for greater freedom.
I like that they have Origin characters, it makes them more fleshed out and interesting to have in the party. I most likely won't play as any of them myself, but having the option is nice because it may help to explain them more if you play as one. Also I can see some people wanting this option just to play them the opposite of how they play themselves, which could be interesting.
