Any work on Elise right now?

Why do people think she has all of this?

She has a one second skillshot stun on a 14 second cooldown and a "troll pole" hop on a TWENTY-SIX second cooldown, neither of which does a single point of damage. "But Terchio, you can level it up for a 10 second cooldown stun at 2 second duration and a 14 second 'troll pole' hop." Yeah, that's exactly why, even after the buffs, her E is still never leveled to level 2 until level 14. In fact, I'm one of the few, as I actually prefer sometimes taking Q last to improve my jungle clear and mobility a shred more.

Her pseudo-sustain is mostly useful in the jungle. In actual fights, your AP has to be very high to get much of anything out of the typical champion, but you also need loads of HP to sustain burst damage, so her AP will be limited. She has probably plus clears, but given her general focus on jungle power, it's not high enough to make up for the lack of teamfight relevance.

Her burst is percent current HP followed by missing HP (and some on Human W). Because of the HP based focus, it really only shines against tanks, as a high current HP will pile high amounts of shredded HP to then re-shred as missing HP. This combo was built for a sustained-battle-approach, but her sustained damage really only shines for 3 seconds during Skittering Frenzy. While on a somewhat short cooldown, it only improves her generally meh autoattack damage (for melee damage, anyway) and adds a pinch more from spiderlings, if they do in fact survive whatever AoE is going around.

And finally, she builds tanky because she has to. She has tank burst skills which require followup procs, and her most reliable squishy assassination requires her to basically hump that squishy right into enemy territory, probably getting CC'd for her 3 seconds of fame along the way. She has to build tanky so that she's not simply a constant fizzle-death to the other team, and yet she actually has no tankiness synergy whatsoever. At best she has slight cover from Spiderlings, but since they will latch onto targets at whim sometimes, they are hardly a reliable source of fodder. She doesn't even have melee values for MR nor Armor, though most of her impact is in melee range. The only tankiness synergy she has is the fact that her natural tankiness is amongst the worst in the game for a champion with as much melee emphasis as she has, which is hardly any type of plus for her.

Really. She just sucks. I play her, I wish she didn't, but she sucks so badly. Some of my best builds have been AD builds, for crying out loud. I used to run Zephyr Elise constantly, and strongly consider going back at times. In fact, I'm back in that rut. She's just that bad.

And don't get me started with the poor synergy with Liandry's that's viral. The only stats she likes on it are the backup ones, as she desperately needs the AP and HP on it (and the MPen is fairly good, but really... Why no Void Staff?). She uses the passive so poorly, as though the Spider Q likes it for more shred, that's typically used early in her combo to net melee range. She rarely does spell damage to more than a single target, and even then the target is rarely CC'd unless you hog red buffs or allies net the kill for you anyway. And while MPen is great for your burst combo, it hardly even effects your sustained damage... almost all of that is physical, even the spiderlings. Heck, she'd be better off with Rylai's, as at least then she can deal more of that sustained damage... and then Liandry's with actual power. However, I never see that on her for some reason, though its AP and HP stats are far greater. Makes no sense.

All in all, she's not this "jack of all trades" you make her out to be. She has some strengths, but hardly anything to gloat about with her glaring weaknesses, such as basically all single-target damage and CC, poor natural tankiness, and a generally predictable and unwieldy kit.
