You beat a Teemo mid, good for you. I'd be surprised if you lost.
I have played her recently, many times in fact. I'm talking in the overall grand scheme of things, outside of lane phase.
Lane phase, she's fine.
Outside of Lane Phase, she's lackluster.
I know to keep moving, I know not to place sphere's merely for the ulti, her damage, overall as an AP carry, is inconsistent. You're telling me the basics of Syndra, meanwhile, she still has some glaring problems that stops her from being a Grade A pick.
As for Q dodging, it's like dodging Cass's Q, semi-short range, and pretty easy to keep moving from. The trick is predicting where they'll be, not where they are, but the shorter range of Q, combined with it's delay, makes it rather easy to dodge, because I've played as Syndra and against Syndra.
She is still useful in teamfights, what are you talking about? A team-wide stun for 1.5 seconds can be huge.
Q isn't "short range" and since you move while casting it you're only in their range for a second before you're gone.
Syndra vs Syndra is tough, because Syndra is good and if Syndra is also good then Syndra has to be faster than Syndra or else Syndra will land her Syndra spells on Syndra and Syndra will die to the OTHER Syndra.
In a situation like you're describing here, your ult should be the killing blow. No ignite should be needed unless you didn't set this up right.
Don't place spheres for the sake of my ultimate? If I'm in lane and I know a fully built ult is going to kill them you bet your ass I am placing spheres all up in that ****.
Always move is really not a strategy for this champ. It's a strategy for League of Legends and all MOBA's really. If you don't keep moving, you will die.
That's not always right at all. If you play properly you predict your opponents moves and know they will throw their **** behind you with the intent for you to run over it. That's why you don't do that. Unless you bad.
And situationally, you can place spheres for the sake of an Ult then Flash+Ult them. You misunderstand: In game, don't place spheres with the sole intention to build up the number of Spheres Unleashed Power will use. Anyone who stays to fight you when they know you can kill them with 1 ult is stupid! Plus, if they see you placing spheres for no reason, they'll know exactly what you are planning and escape.
Always moving is a strategy for Syndra, never stand still while casting. How many other champs can attack while casting, and move while casting? Sona? Don't stand still after you cast, move out of their range again, use this to always stay safe with your superior range and mobility. The only time you can handle someone being close is when you're going to ult them, or Stun them.
I'm not saying alway throw a sphere right behind them too, but when you're poking in lane, it works, unless they're moving side to side, then you aim differently. But if they're auto-attacking, then they'll back up into it!
