It would be great, if Lissandra could use her ultimate on allies

I think this is a bad idea, for two reasons:

1: It would add a lot of power to Lissandra, which means she'd have to get nerfed in other ways.

2: Your teammates might not want to go into stasis, that might seriously mess up some kills or even get them killed in certain situations.

Dat troll ult tho lol.

well,with the odd ultimate recently added,why not?

She's gonna need drastic damage nerfs tho.

The troll potential is more than bard's and tahm's Why would you turn and brainless high dmg and point and click cc Mage into a support?

I've looked about the damages of the mage (not real support) champions who are often seen played bot:

Brand. 1118 base + 8% of enemy's max HP. 2.45 AP scaling. Additional R ticks add 350 + .5 AP scaling, for a potential max of 1818 base + approx 12% max HP, with 3.45 AP scaling on a single target.

Annie: 895 base +2.15 AP scaling + .2 from W and + .2 Tibber's aura.

Morgana: Between 1350 and 1550 base. 3.4 to 3.95 AP scaling. (Pre nerfs Morgana???)

Vel'koz: 1880 (!!!) base without passive. 2495 base with passive. 2.95 AP scaling. All AoE.

Lux: 1000 base. 2.05 AP scaling. Add 190 per passive proc for a max of 760 additional damage.

Lissandra: 1045 base. 2.55 AP scaling. All of it's AoE.

Liss doesn't look like she would break the game or something, if she could ult the adc and heal him/her...
