Well it's like this, Tri had it so after you had filled your spirit gauge, it would let you infinate spirt slash till after the set time then usage started happening. Also after you got Gold Blade, the blade stayed charged gold till you either spirit combo to Red Blade or die. After red though, you had a set limit to how long Red Blade lasted. The big changes to LS in 3U are using the spirit gauge, even at full charge, starts costing spirit. Also, the Blade Charge has a visible time gauge to tell you to spirit combo before blade charge is gone. Unlike the Red Blade in tri though, when you finish a spirit combo on Red Blade, it resets the time. Hypothetically, with enough spirit gauge, you could keep Red Blade through the whole fight. Wether these changes really do effect how everyone used LS in the past and now, I guess we will find out.
