At its core, this strategy primarily breaks a core tenant/rule of the game - investing more deeply in a character should always be better in terms of gameplay outcomes; more health, more damage, more functionality, etc. This is a game about strategic resource management and you should be rewarded for strategically investing in a character. People who did this investment were then punished, because there is no way to “level down” a character. This doesn’t always perfectly hold up, but we do our best to hold to the spirit of that core pillar as much as we possibly can.
Apply this to Territory Battles and Grand Arena. Galactic Power was added for TB, and growing one’s GP is needed to win. Then comes Grand Arena where high GP is a detriment. People exploiting undeveloped rosters for lower GP matchmaking is hardly any different than choosing to exploit an undeveloped NS Zombie. Players should be rewarded for growing their GP to help their guild in an established game mode. Just like Zombie, one cannot strip gear down once placed; one cannot choose to lower their GP to get fair fights in Grand Arena.
The matchmaking algorithm should at least be matching people with similar gear levels (e.g., G12/G11), while preferably also cross matching similar characters (e.g., Revan, Traya, etc.).
