Electro Leap: What It Counters

I definitely disagree. Its super easy to protect a strider from melee.

I mean now we are just speculating tactics in a vacum which is not going to get us anywhere. 

There is typically more on the table than Jacks + caster + chior. Having to keep your entire backline 4+" behind your jack line can be obnoxious and exposes them to flanking threats and such. Striders threat farther than our jacks typically and in a good Nemo3 list should have arcane shield and +2 arm from nemo meaning at range we need battle to exchange shots. Its a lot more intricate than you are making it seem. I have played the match up twice now with my durst list (a list supposedly designed to face down dedicated gunlines) and its rough. Even arm 25 jacks can get hurt on Nemo's feat turn 

Also remember the Armory objective is a thing, and it sucks.

Few. Most take Arlan Strangetouch, though, and he can give out Magic Weapons too. And if you run A&H and Arlan, well...

RE leaping onto support from jacks, this is why I tend to play Creator's Might into Cygnar. It's lambasted as a weaker theme force on the Facebook group but I'll tell you that Reposition 3" on Choir and solos is serious money when protecting against leaps. It's still not hard for Cygnar to remove the support when they want to, but they actually have to focus on that and, as said, it isn't super easy to run a solo into the back line and zap the support when there's a bunch of crap in the way.

The problem I usually have with the Storm Strider is that it has Dual Attack, meaning it can threat 22" onto a valuable target. Doesn't matter how far back I leave Durant1 from his Redeemer, the Storm Strider can get there in two turns. I had to stop playing him in my Cygnar pair because of how vulnerable he was. This goes for the Choir too - one good 14" shot and a favorable Lightning Generator roll can toast an entire minimum squad instantly, greatly weakening the Protectorate counterpunch. 

Shows what I know! Does hurt on Dynamo, though. Boy's a dang hoss.

we have a player who is pretty much dedicated to the nemo3 storm division lists. Unfortunately, I do not have enough protectorate jacks to run the full creator's might list I'd like, but I have faced off against him with my Skorne Imperial Warhost Xerxis2 titan herd list and ground him into the dirt a few times. It took me awhile to realize how to take care of e-leaps but it's really just purposely allowing them to target specific models and then putting a lightning rod right next to it. You don't need to worry about 4 inches when the vast majority of their e-leaps only bounce once. Just make sure there is another model closer to every model than the choir models. Even then, he still messes me up with Nemo3/firefly and his damn storm strider. After I started to pick apart his lists though, I slowly unlaced the knots and have a general good understanding of how to beat him. The solos he brings are annoying as piss. Combining Journeyman's 3 arm with the iron zeal on his stormblades efficiently gives them a turn of survivability even while they are standing face to face with a titan, even more so when nemo3 decides to drop electrify on them just to piss me off.

The key to stopping the list is both simple and, well, annoying as hell. put your poppy units either outside the threat range of or on the other side of the table from the storm strider. Target solos and fireflies before focusing on infantry... 1 round the strider if you can, even if it means sacrificing something important (got tired of being assassinated by it) The infantry isn't scary on non-mini feat turn and without support.

Durant2 and VoJ combo should be able to do this much, much easier than a titan herd. FFS, Durant2 has Xerxis2's feat as a basic spell x.x; You don't need to worry about taking a bit of hurt from the first few turns because, well, you'll be getting 2 d3 heals on all of your models a turn if you're playing it right. When engagement happens and nemo3 has all them upkeeps thrown into your face? blessed weapons, VoJ removes upkeeps while healing, good day, good night. after that, it's all about how you decide would be the best way to pick appart the innards of the list, like the solos, the fireflies, and who you are going to sacrifice to take down the strider

Leaps aren't attacks, they can't be SGed.
