@Furious I don't quite see where the difficulty is for for you. The video that was shared does not display any sort of "difficult" or challenging gameplay mechanics the Techer has because the Techer was never really that difficult of a class to play (at least in my experience). It matters more of what you as a player are capable of to pull yourself through the content. The global version already has access to most of that "bleeding edge gear and affixes" and we have already had quite a bit of it available as handouts.
In the description of that video the person also listed the stats of the Wands they used and we have already surpassed those on the global side of things. The only "new" thing you might have difficulty with is the Puras/Stil wand but if you are one of those players who cannot avoid taking damage the Stil's potential is useless (it completely resets upon taking damage and takes time to rebuild itself).
