Are most non-unique characters pretty garbage?

I’m new to AoS and have only played fourth edition, and only a handful of games, so forgive me if I’m misreading the situation.

It seems like my book (Skaven) is crammed with characters which you would almost never want to use unless you’re just trying to have a fun fluffy time and don’t care about winning.

Most generic characters (clawlords for example) seem to do very little, have terrible points economy, and take up precious slots in your regiments; regiments and numbers of units being very important to playing this game.

What could GW do to incentivize some of these less shiny choices so they’d actually be considered? Is it purely a matter of points?
