Is this somehow not a thing yet? The moment her abilities were shown I figured this would become the most busted thing ever, I've only ever done it once and stomped the game easily but shockingly I haven't seen it become that popular. It's insanely hard to kill/gank due to veigars stun and yuumi's heal + MS letting them easily walk away and scales r%%%%%edly hard thanks to Veigar's infinite AP stacking.
How has this not become a thing?
Darkdemon6531 votesVeigar is extremely easy to harass, is very hard to harass with, and has a horrible early game in general.

That weakness of his is offset pretty easily with Yuumi. His early game scales far faster into the game with Yuumi throwing in more damage for him. Tanks are mega ass right now and even despite that 
+ 
is usually enough to 1 shot everyone who isn't a tank.
Maybe it's just my 1 game experience with this particular strat making me think it's OP
ThatHookAgain1 votesHis early game doesn't scale at all. That's why its early. A scaling champ is meant for late game. Unless you have a duo with a jg who will keep tabs on you. You will get pushed and killed often.
ThatHookAgain1 votesCrappy early game. No tankiness. Loses to anti enchanter unless you position Perfectly everytime. Theres a lot of holes to this cheese bro
Anxious Veigar1 votesVeigar + any mage bot is very good.... It's not a secret, (mid Veigar sucks, bot Veigar is good) also GLP is much cheaper, better and gives more utility and burst.
Baby Ghoul1 votesVeigar is way too easy to bully. Yuumi's harass and safety is broken, but she's not that broken. You'd have to be against an ADC that is really weak early game, like Ezreal, but even then, he's the safest champion in the game. So I don't know if you'd end up dominating that lane, and he turns into a beast late game that neither of you could compete with.
If you're against something like a Draven and an aggressive support, then that'd be a GG real quick.
Yuumi also is far from the only BS support bot right now. She's in good company with supports like Pyke and Brand, who could both obliterate that combo without much trouble.
