What is mediocre about GS?!
If Tira stayed in GS 100% of the time, would she be on par with Hilde, Algol, Setsuka, and Amy? The answer is clearly no. GS just makes her an average to above average character. She's not strong in GS. The characters just mentioned can deal more damage with better speed, range, and safety. And when you factor in that the moveset gears her towards JS more often than not, you are fighting uphill non-stop.
So the point was to either make GS the best character in the game or make both JS and GS better.
