This is a suggestion for Galactic War after experiencing the remake of it.
Why not have every 3 nodes with the same faction but with different lineups? That way, we can actually test our toons against the similar faction opposition.
So for example:
Nodes 1 to 3 can be Ewoks but with Chirpa lead at Node 1, Teebo lead at Node 2 and Chirpa lead with a different lineup from Node 1, at Node 3.
So it makes you think through how to stop their synergy and to also give players experience in dealing with such synergy should they encounter it in arena and/or Territory Wars.
Alternatively, you can do it by Systems and grant bonuses to specific factions at Nodes 1-3, 4-6 etc etc.
Instead of fighting a ridiculous combo such as Rey Scav (L), Jedi Consular, Talia, CW Chewie and Princess Leia, we could actually help the player base get familiar with synergies.
