the point is that vanilla did some things better than its remake in regards to pvp, such as its interface, its more balanced and weaker cards, and a more aggressive and rewarding game style and focus on map control rather than turtling.
these are things I hope de will adopt among other changes to make a more fun and engaging meta. meanwhile patching out hacks in legacy will also do so much to help the pvp experience there and bring in lots of goodwill.
