So, with new patch notes saying "- Fixed Neutral creep chase time being too long.", the whole pulling and stacking mechanics is different on test right now.
After reading about noLegenD research on reddit, I thought I could focus a bit more on some pulls, namely
a) dire easy camp double pull
b) radiant middle lane pull
c) radiant top lane pull
What really have changed (read "you can't do it anymore soz") is the ancient pulling into dire bot lane and the exploit used to farm ancients blocking their path with a courier, but this is a true bugfix so it's only a good thing.
Let's start with the post.
a) Dire easy camp
Now to pull the camp you have to:
Attack a creep at X:06 or X:36
Quickly move to this spot and stand still untill you receive a hit from the neutrals. This way your whole creepwave will be pulled into the camp, instead of just a single creep
Pulling the big camp is still possible, even if it's SO much harder because you need to have perfect timing now, the neutrals need to arrive at the small camp perfectly when the last creep dies, otherwise they won't take aggro (you can stand when the Troll is in the picture to get hit but perfect timing is still a key factor)
That's all for this camp.
b)Radiant small camp
The key factor of this pull was that you could pull the big camp at the bottom into it, completely denying every form of experience to the opponent. Now you can't do it anymore (I mean, you can but you have to destroy quite a lot of trees under the camp and you need some spells like vacuum, skewer or firefly).
You have to double stack it before pulling now, that's the only way you can do it with a support.
Like the dire side, after cutting some trees with a quelling blade or some tangoes this time, you need to pull the camp at X:06 or X:36
Now you have to move to this spot, near the small plant texture, the creepwave will follow you and the neutrals
For every pull, you will probably have to move inside your creepwave when the attack from the neutral starts, in order to prevent the creeps to not being aggroed
c) Radiant top lane
This is by far the easiest to pull, you just have to cut the same tree, and maybe the one in between the lane and the camp, even if I doubt it's needed, and respect the timing, which is not that big of a deal.
The pull is started by attacking the neutrals at X:21 or X:51, quickly falling back to this little spot
