It does not “blitz” minion waves down in the laning phase, especially early on. What it does is it fucks up the health of creeps at your tower, making it likely that one tower shot will take out a creep, while leaving enough health to make your auto-attacks take too long. The solution in early game is to not pool the creeps at all, or pool the casters in a fashion that you only get one or two ticks off while they’re moving to the tower.
Secondly, you shouldn’t be scared of AP Janna. You negate her CC and her damage because, if I remember correctly, her cooldowns are quite high and she shouldn’t be able to hit with anything bar her little sprite thing-y. So you get in her face. Okay, that’s not ideal positioning for Morgana but the choice is to use your superior damage (even through her shield) and your hefty sustain to stay in the lane and bully her out of it. This does, however, mean no pushing and no using pool. You will have to watch for ganks, though.
Not being scared of Janna, or not being able to be killed by Janna, does not matter. Neither champ kills the other. The lane is a farming/pushing match-up and that is it. Other threats are external, from ganks as you said yourself, and if you want to get in Janna face you’re either dead or you’re blowing a flash.
Your “superior damage” is dependent on that skillshot. Without it landing, you don’t have superior damage, you have an ult that does middling damage at level 6 with zero bonus AP, an ult that is part of a kit that keeps you from getting ganked. Guess who else has an ult that counters Morgana’s ult while providing a buffer from ganks? That’s right… JANNA. It even has the same cooldown as Morgana until level 11, where Morg gets 110 seconds instead of 120.
Range of Morg’s leash… 1000 units. Range of Janna’s pushback… 950. 50 units is more than enough for other factors to determine that your leash fails. Indeed, Janna can just start walking WHILE you’re being pushed back and guarantee a leash break with no problem. It happens all the time if you ever played Morgana against a team with support Janna, another reason why I think Morgana is overrated as Janna is a very popular support.
You can manipulate the minion waves a bit. Walk in front of yours before they arrive, hit Janna to pull their position around and disrupt yours and so on. This is not close to a usable solution (more useful in HoN, I guess) but it’s something to think about. Position disruption and zoning are really, really important for Morgana.
Not only is it not a usable solution, it’s a terrible solution as damage from creeps is very relevant to levels 1-6.
That’s what I’ve got off the top of my head. Between Black Shield and positioning, Janna shouldn’t be doing damage to you. Binding and Pool mean you can damage her for very large amounts and you have sustain and she doesn’t. Pool and auto-attacks should make farming easy as Morg has a better auto-attack.
More theoretical mumbo jumbo that forgets that what Janna lacks in auto-attack by a couple of numbers, she has a shield that blocks creep damage.
And for fuck’s sake, BINDING DOES NOT HIT PEOPLE THAT ARE NOT FUCKING RETARDED.
Oh, I haven’t checked the mana numbers but I seem to remember Janna being really, really mana-hungry so again, careful play should help you here.
Morgana is equally mana hungry with very long cooldowns. Her and Janna aren’t much different in that regard.
I don’t need to say this shit again. It’s not a matter of dying to Janna or kill Janna, it’s a matter of not losing your tower and not losing creeps to it. Janna has no problem whirlwinding complete waves and having the range to take out your melee minions and caster minions with auto attacks while being able to retreat to safety. It’s the SAME EXACT ADVANTAGE that Morgana has, only she farms the wave faster at puts your creeps at odd health levels for tower CS.
