Sorry for my English. And hello, though i'm not sure about greetings.
0)Keep in your mind: i'm unranked, though i playing to LoL from April 2014. But i'm not so experienced than Scarra or Dyrus.
1) When new jungle items (i mean 
Skirmisher's Sabre and 
Stalker's Blade) appears, 
Tryndamere becomes more vulnerable.
[1]
It's funny and even cool. Especially for unexperienced players. They were can't counter Tryndamere, like 
Fiora or even 
Master Yi;
2)After jungle rework, 
Warwick lead all the records in banrate. For 1 December 2014 his banrate is 91.02%. [2]
Okay, jungle camps becomes more stronger than early, in Season 4. New jungle more like for tanks, like 
Jarvan IV or 
Sejuani, The Boar-woman. And WW, of course.
I think, 
Void Lurker will be feel in that jungles like in home. But 
her hole systems shall be hard to master. I think so.
Also, 
Pantheon and Fiora by their 
Aegis Protection and 
Riposte can quickly take 
Dragon Slayer buff. I don't know, what think about it;
3)Okay, 
Kalista is out in 11/19/2014. And she is funny, but weaker than 
walking crematorium. Her skill kit like Sivir's and Ashe's. That's make her weak. She is more helpless without ally. From one side it's cool, you count on your teammates. From other side there is many duelists, which can alone stand against nor only assassins, but even against all other non-tank champions. Like 
Irelia, 
"I want to punch something" girl or 
"To the sky about three" guy from fighters. And 
Vayne, 
Twitch, 
Yordle & Machine and 
Jinx from marksmens. I think, they're a best duelists.
I don't check, how Kalista stand against 
Quinn and 
her pet.
4)If i shall talk about fanon, then take heart.
After Kalista's release she'll be paired with 
Thresh [3]. And there is only one trouble: Thresh in some fan-art displayed as blushing boy, when standing together with vengeful conglomeration of souls. That's funny, but little stupid [4].
There was try to show Kalista as matchmaker, especially when she was supported by 
Sun Knight [5]. She trying to pair is Leona x 
Diana [6]. That's be funny, but obsolete. Because you know, how 
"fling skill" works? Kalista summons ally (okay, not summons, but make him untargetable spirit), and that ally chooses, to which direction he will dash;
Okay, thanks for attention! Sorry for my stupid thoughts and ideas maybe. Good luck! --
