By looking at the changes made for 6.74 DotA release, we decided to jump directly to that release. All heroes Item Builds are done, the new item build system is in place and things looks like working smoothly. Well there maybe some unusual stuff going on from time to time.. but that`s considered normal. The new items system tries to mimic human behavior. Builds are being built by stages: starting, core, luxury stage. After core, AI picks up random luxury items... more variations. Cloud_str, Green, gaibo and Simple went to hell and back making that system working.
Well, release date is close... if nothing crucible happens after 6.74 porting ofc. Stay tuned, wait is almost over.
