Worst mistake ever done in Battlefront 2.
Can't stress the fact of how overpowered are these 2 factions are in the field. Weapon damage values are off the charts when it comes Empire vs rebels and First Order vs Resistance.
-For instance...A Stormtrooper main weapon will start giving lots of recoil while the rebel counterpart doesn't which brings in a huge inbalance between the basic assault classes.
-Rebel & Resistance heavies are extremely overpowered in terms of damage output and damage intake even when Imperial or First Order units are using the T-21.
-Officers are like minor reinforcements to these 2 factions, while not as overpowered as the rest, still very formidable and can shift the balance of any match.
-Specialist class broken abilities (All infiltration weapons) while Empire and First Order struggle to become formidable infiltrators.
-Rebel and Resistance reinforcements are also extremely OP. Their aerial units acts like buffed snipers, wookie warriors have the slam and thermal imploder that doesn't hurt the unit while the Death Trooper Specialist gets damaged by it's own grenade.
To fix these factions, it's better to add recoil to their weapons so that sustained fire causes accuracy issues to balance things out.
