is morg support good?

She is but she lost a lot of popularity recently due to carry supports such as and being very meta right now. They have a lot of dmgs so they can bully morg and her adc and their spells also pop black shield like a balloon (unless she max it first).

Also, enchanters don't really rely on cc for winning trades.

She's basically a massive hard counter to disrupters.

yes.. she is good for her cc and zoning.. her ult is great if you can pull it off in a team fight. she is a good counter pick to certain lanes...

I have had great luck using her as a full damage build like Brand and Zyra when I want to use her as a carry sup. I Basically end up builder her like i do lane Morg when I'm done wth , but I'm in lower silver where carrying more is probably more usefull. I'm sure at higher elo the more sup oriented Morgana is better. Bascially same build I use for lane just replace sup item with Nomicon.

Incredibly strong, just go and you are set for the game.

I enjoy her as a utility mage with decent waveclear.

I used to play her as a carry support and do really well. She's still good and her shield is nice unfortunately I think is currently a better pick.
