In case you were worried that getting 10+ kills prior to the 20 minute mark was a problem.

Obviously, you're not going to get 10+ kills before 20 minutes have elapsed every single game, but you will get a lot of kills nonetheless (at least 5 or 6 usually).

Each additional shatterglass makes it easier to get kills (and thus gold) because it helps you overcome any tanky builds that might be able to withstand Joule's ultimate. Therefore, accumulating gold becomes pretty easy late game. Thus, getting 3 shatterglasses somewhere between the 20th and 25th minute isn't too difficult. And i concur that the notion that this build would take 30 minutes is absurd.

If you replied to the comment, you should notice that's LotusThunder not me. I was approximating that in general if you have around 10+ kills, you should have enough gold to purchase all those items. LotusThunder had around 10 Kills in the posted screenshot. It would have exceeded 10 Kills if the match had continued. If you read the posted guide, you'd see that Late Game (~Minute 20) corresponds directly with the posted screenshot. If the match had stretched onwards for 25-30 Minutes, the third Shatterglass easily would have been purchased. In fact, it shouldn't even take that long. Anyways it sounds like you agree, so I'm not sure what "bluff" you are calling.

He wants them to focus on him, so he can score a Triple Kill. Focusing on Joule still won't work the majority of the time. The premise that Catherine with Stormguard is a solid counter to Joule is not quite correct. Joule is a hard-to-play character but when played properly is easily an ace. With the new update making her tankier, she'll be even more OP. Every build will clearly have weaknesses and advantages, but this is a balanced build. The initial commenter was also incorrect in stating that three shatterglasses before 30 Minutes is nearly impossible.

If facing Catherine, you always have the option of keeping your distance in the lane and/or activating travel boots to escape her stun/silence abilities.

In the event that Joule is in the jungle, Joule would also be able to simply run away after Catherine hits her with a stun/silence (I'm not convinced Catherine would have enough damage dealing ability with her basic attacks to overcome Joule's Heroic Peak before Joule is able to use Travel Boots post-stun/silence). A Catherine counter only works if she has someone else to deal damage alongside her after a stun/silence AND Joule doesn't have ally heroes nearby.

In a perfect 2 v 1 or 3 v 1 scenario where Catherine is able to land a stun/silence and then activates Stormguard alongside a hero with damage dealing abilities, yes she would win. But no one would be able to survive a perfect scenario such as this.

In no way would Catherine (alone) "counter this very well"

It's possible for any 1 hero build to be defeated when all three of the enemy heroes are focusing solely on taking out that 1 hero.

Furthermore, Joule's Heroic Perk is rumored to be getting buffed. So she will be tankier in version 1.22
