But lets just look at words. Words are easy to understand for everyone while graphs might require your attention. They are 128 toons in this game : 75 Light side / 53 Dark side.
32 rebels / 15 imperials.
23 galactics / 10 separatists.
6 resistances / 5 FO.
7LS scoundrels / 9DS scoundrels.
0LS / 6 DS bounty hunters.
5 LS jawas/0 DS.
7 LS Ewoks / 0DS.
3 LS Droids / 6 DS Droids.
19 Jedi / 9 Sith.
6 LS Clones / 0DS.
In 2016, 20 rebels (counting Rogue One rebels except Pao and Body that went after). In 2017 they are 32 while they were already outnumbering any other faction in this game.
2 rebels for 1 imperial, 2 galactic republic for 1 separatist, 2 jedi for 1 sith, etc... the only opposite is 1 LS droid for 2 DS droids and we know DROIDS ARE META...
50% more LS than DS but no, there's no specific love for LS, they just happen to benefit from the right time and moment, did they ?
No need to explain what faction will get more love when The Last Jedi come out, or the one who could be the more OP to clean the game and each content of it ?
And no need to explain why the next TB will be LS again (just in case, it will be because "lack of DS chars").
