When we inevitably get a level cap raise, I believe we should get a new updated Galactic War option, Heroic Galactic War.
Heroic Galactic War unlocks once you are able to sim regular Galactic war and are lvl 85.
Heroic Galactic War will have 12 teams as well, however it will be much much harder, for example 4 g11 teams, 4 g12 teams, and 4 g13 teams (chosen from random arena teams with the gear requirements). It will reward deep rosters.
the daily total drops will be 2400 tokens, 50 crystals, Rare Salvage, and the final node drops 5 shards for a new exclusive character only available from Heroic Galactic War.
This will replace Galactic war, so one would have to choose between the two.
