I don't agree that it doesn't play any differently, there are 2 more VP's resulting in more reasons to attack certain points. A player that maybe struggling early game but in a 3 vp game can come back, the chances in a 5vp game are diminished incredibly, we saw Noganno throw in the towel twice and both were under 25 mins (one was under 13 min) despite both games previous being over 40 mins.
That's a massive difference and one that gives a huge advantage to certain players/playstyles that no other map gives.
After countless practice games on both normal and 5VP crossroads i can assure you that you dont approach the map any different. I didnt watch the grand finals yet but id be suprised if 5VPs made a huge difference. If Noggo loses in 13 min on 5VP crossroads then he would have lost on normal crossroads aswell.
As i said, all it does is cutting down the time available for a comeback once one player is dominating. The area around the added VPs infront of your base always has been important to control your opponents movement and ressource income
If any map should be looked at on its influence on the game it is Bayeux and the insane ost dominance on it
