For me it’s a huge game changer, I’m in wvw 90% of the time. I spend about $20 a month on gems, just to upgrade keeps, towers and SM and throw down Catapults, arrow carts, ballisticas. I won’t be doing this any more and it’s simple, Your towers, keeps and Sm are gone before you even have time to react. Why update much less throw down siege equipment , It’s a big waste of money and resources.
Those who defend this move are certainly not the ones standing around looking for the enemy to show up and when you call it in they may show up or they may not. 5 was a good number. There were ways to seige with 25 people without showing the gold swords, if you knew how.
