It means the builds listed on champion.gg. so there are "champion.gg builds". They are builds listen on champion.gg lol. It doesn't matter if its player-made or data-mined.
It took 3 patches for people to stop building near full-tank on Vlad. People are still building Protobelt over Abyssal, when abyssal is actually broken right now, and Protobelt just got nerfed.
People are still running TP+Flash instead of Flash/Ghost. The full AP build isn't even using ionian with that combo, when summoners are what allow Vlad to function in teamfights.
None of the builds let you hit 40% CDR. Neither 'common/best' runepage has CDR in it at all.
The Vlad players are actually letting Maokai, Darius, Poppy, etc lane.
Finally, the current patch just hit. Using champion.gg for data right now is actually braind-dead retarded if you're trying to say champion.gg is reliable. Mostly inexperience players play him, which is why the builds don't make sense. There's only 42 games on the 'highest win-rate' build. Wait a week or so. It'll go back to tank most likely. Happens pretty much every time.
