Rek'Sai has officially taken the top lane away from me. I haven't won lane against her in a single match, even playing as Jax I lose. All she needs is a vamp scepter and that Q lifesteal begins to take place.
I'm gonna post what I wrote about her before she was available
Did I nail it?
From just seeing her abilities, I can tell you already what I think her main strong/weak points are
Pro
-She can clear jungles exceptionally fast, since if you create a bunch of tunnels you can literally move from camp to camp, your W deals AoE dmg and stun, your Q hits all the enemies around you for 3 times and your E scales off your fury, dealing on max rank 240% your AD as true dmg if you have full fury bar
-By leaving a tunnel (or making one at the moment (her E)) on strategic places (enemy's camps, enemy's bushes, ecc.) She can have great map control, leading to unexpected attacks/ganks/escapes
-She's manaless and her passive let her self-sustain by consuming fury
-She can lane too, since not only she can poke with her Q, self-sustain with fury and follow pretty well in ganks, but she can also avoid enemy ganks easily thanks to her W giving her vision, speed and no unit collision and her E
-She can detect enemies inside fog of war (as long as they move) and can check brushes with her Q
-If she gets a teleport, she can easily gank another lane and immidiately get back to his own thanks to her R, wasting no time at all
Contro
-She's basically an AD DPS bruiser who can deal true damage, thus not being that much useful in teamfights (she's not like Olaf who can shrug off any kind of CC and smack his opponent 'till his (the opponent) death)
-Her W can work against her: if enemy is waiting somewhere without moving, you can pretty much walk inside their full team and end annihilated
-She can poke, but her poke not only scales off AP, but can be used only during W and it is more useful as a way to check places than to wear somebody down
-While in W, you lose fury if you don't have full health, making it difficult to get a full-fury E on enemies
-No CC: she only has her W stun
