Among all the criticism (part of which is surely well-earned) I'd like to just point out one really great node design I found in new Uncollected EQ.

It was partly limiting to champions which you can use there thanks to Pull node but rewarding on the other hand to a lot of others. Seeing some ridiculous numbers was really great too. Matador was good fit to finish the combination and Masochism could be considered as challenging part of the nodes so it would add some difficulty.
Seeing something like this in for example 6.4 on much higher health pools could be great fit for fun but challenging content which we all really want IMO.
In conclusion kudos to whoever came up with this idea. Give him a pat on the back for me.
