Stab weapons through the ground without bouncing. Attack next to walls all day without being stopped. Overhead straight through teammates without hitting them. Spin 180's while stabbing people. Spin 180 while overheading people with a pike (aka long spear) through teammates while next to a wall, sheathe it and switch to one of your other three weapons.
Being level 42. No color-coded chat log. No score, no valour. No banners on scoreboard. No banner-balance. No proper custom banners. No DTV/Rageball. No such thing as "crossbow spec" (at least, wpf didn't improve accuracy at all). Vastly less armor choices. Less weapons. Heirlooms giving percentage-based bonuses. Everything people complain about being OP now was vastly better. No official NA server.
Good riddance.
