felipepepe C&C-oriented games generally, I think the answer would be "less gameplay," but in this case, it's definitely "better gameplay."
Tyranny doesn't have all that much trash mob combat: most fights make sense for what you're doing. You are in the middle of a war, attempting to achieve objectives some other party wants to stop you from achieving. Some of the set pieces are even set up rather nicely, such as when you're storming a fortress or occupying a village. The problem is that whatever you do, you'll end up with a roughly even mix of weaksauce attack, healing, and escape abilities, and you'll be facing enemies with the same. So gameplay is just a grind of chipping away at their hit points while keeping yours topped up.
As it is the gameplay is a knock-off DA:O by someone who doesn't understand what made DA:O tick. While DA:O is still cooldown-based awesome-button derp, the abilities have obvious impact, marked differences, and you're facing enemies which shake things up. Fighting a revenant is not like fighting a dragon, which is not like fighting a mob of genlocks, hurlocks, and emissaries, and each of these will play differently if you're rocking two tanks, an archer and a healer than if you're rocking one tank, an archer, and two casters (times any of the other party combos that you might want to think up). If Tyranny 2 had abilities that were up to DA:O standards and different mobs had different mixes of them, there could be a quite a lot of fun to be had despite the cooldowns and skill trees.
Or, counterfactually: if Tyranny had DA:O's core gameplay and abilities, and the exact same encounters that are in it now had the enemies using different and thematically-appropriate mixes of them, it would be a fine game. Like having Disfavored bum-rush and shield-bash with their mages lobbing Earthquakes and Stone Strikes, while Scarlet Chorus featured javelin-lobbing, fast-moving skirmishers and their mages using Nightmare, Drain, and what have you. You wouldn't just be fighting on different sides, you'd be facing a fight that also
felt different.
