Morg has a point and click AP SPELL SHIELD, which is more effectively used against mages who are usually mid lane.
Morg has a longer snare by about 1 second, and it only effects the first target.
Her passive was always sustained base.
And her ult is centered around team fighting.
Lux was designed to have almost the same kit.
Except her passive is poke based.
Her Q can snare two targets indicating she belongs in a double lane.
Her W is a normal shield, and the strongest one in the game, it is also aoe which means she can shield more than one person.
She also has an aoe damaging ability, except hers allows her to zone enemies off farm and acts as a slow for extra peel.
The only thing Morg has over Lux in the support department is the ult.
Which is because Morg is a battle mage. Lux's ult is designed to snipe kills when the person gets away so they dont survived, or to help far away team mates she wouldn't otherwise possible and something morg cant do.u
