Timing Out with Combos

So I'm curious if anyone knows why this happens. 

I just lost to a priest combo deck that should have timed out long before the combo killed me. I've done similar combos, but I have only got them off maybe once or twice before I time out. 

My question is this, how can you not time out?  I'm actively doing the combo... In playing cards... I have a great and fast connection... And my processor is moving fast.  So why is it that some people are able to get their combos off, while others are held strictly to the time?

Basically your opponent plays their cards before the animation ends while you see full animation.

Even though it looks like rope already burned from your perspective and he/she still playing cards in reality your opponent done with the combo before the rope.

Its not related to your pc specs or anything its just how hearthstone works

This is always a challenge for me with wild mech OTK.  My advice is don't concede, it takes some skill to execute and they may eff it up (I know I have with the bot OTK)

As p already stated, it's just animation time.  They play cards within the 90 second time limit (or whatever it is), but Hearthstone will show you all the animations for those cards played, then you get your turn after you see what was played.

At least it isn't like the old days when your opponent could eat up your turn through the animations.  Norzdomu was a key culprit of this exploit originally, but over time other combos could be used to still eat up your opponent's turn through animations.  As late as Un'Goro this was still an issue: https://www.youtube.com/watch?v=GtWVR-FYCf8

I think they FINALLY fixed this for good around the release of Shudderwock, seeing as some turns could take a long long time for all the animations to be completed.

Thanks for the answers on this... On the note of the animations, is there a way to tun those things off?  I just want to be able to do my combos as well before they time out. 

No, you can't turn animations off.  It's a part of the game, and if you turned yours off while your opponent kept theirs on it would give you a distinct advantage when trying to play card combos that have extensive animation times.  Or vice versa if your opponent had them off while playing a combo deck.  It would essentially give them more time because they aren't waiting for any animations.

If they did have a way to turn them off I imagine they'd have to shorten your turn time slightly to make up for the change, effectively negating any advantage you might gain in turn time by eliminating the animations.

If you are having trouble pulling off a specific combo such as APM Priest you may just need more practice with it to ensure you know exactly which cards to play, when, on which minions, at what times.  I personally don't play APM combos like that one, but in watching streamers like Dog it does seem like you need to play without hesitation, which can be easy to make mistakes if you aren't well versed in the order of play you need.  That kind of speed only comes with lots of practice.
