I understand your point but if combo is what you want then it's not really gone, it's here in a way and better than before.
Think about this for a second, earlier every power had one global cooldown which meant you had to use your and your squadmate's ability to chain combos. A|t max you could chain three abilities, one from each squadmate, provided the squadmate didn't use their power recently and it's not on cooldown. Here you have individual cooldowns on three of your powers which are completely under your control at all the times and you can once again chain 3 abilities at max.
Granted you had access to 9 abilities in total in previous games between you and your squadmates there's the fact that if you want something other than the three abilities in Andromeda then you can switch profile to a different preset from the weapon wheel. Using the weapon wheel mid combat was something you already did in previous games...you just do it far less here.
Tl;dr: Combos themselves work better here, but the ability to decide when your squadmates use what is definitely missed.
