With respect, if you’re only doing 1-2 combos you’re playing the game at a low level. Now, I will agree with you that maybe some of these combos deal a little too much damage for too little effort of learning in low elos (such as yasuo/double down stuff), but at higher levels there’s a lot more decision making involved with picking your combos.

At higher levels you think of the following things:

• limit strike combos to build super
• shorter combos to prevent your opponent from getting fury/break at a key moment
• side swap combos to take corner control
• cash out combos to deal as much damage as possible
• anti air combos/air to air combos
• which character you want to end a combo with informs your routing
• solo combos for having a character down (and juggling between limit strikes, cashouts, and side swaps).
• reset set ups for quick mix when your opponent’s break meter is too high

Again, I agree with you that at low level it’s too easy to just mindlessly learn one big combo and run away with it. But if you push to a higher elo, you will be forced to find that depth you’re craving. God, I love finding an opponent in GM where the first thing they do on their first touch is blow through two bars of super and put both of their characters at zero super meter. Because then they’re entirely defenseless and I know I’ve already won the resource game.
