A comprehensive guide to fixing these imbalances behind the dashboard

I agree with OP here. There is just too much damage and people are just concerned about speed. Reducing the speed of some characters (i.e. Poe or Rey) won't be a solution. The cannons WILL attack you eventually and one shoot whomever they want to. If defence and armor is increased 'defence up' and 'armor penetration' buffs will be at least as useful as 'off up' and 'crit up'. This may change the game a bit and make us think on different strategies (instead of "1 taunter + 4 dps") thus making it more fun to play...
