1) 2 minutes times 25 battles per day? That's a HUGE increase in time, sorry, not interested.
Lets say a fight lasts around 3 Minutes, now let's add 2 Minutes to that. That's 5. Let's now add 2 Minutes again for before & after the fight, searching for an enemy etc. That's 7 Minutes. With 25 fights that's only almost 3 Hours. 3 Hours, that's absolutely nothing for people more dedicated like me, and it's not like my ideas are made for a casual audience.
2) You claim you don't want to make it longer but then your ideas make it longer. People of different abilities play the game. Right now competitions are based on your skill of picking a time and that team's abilities. Very little is based on player dexterity and that's good. If anything they should get rid of the mini game that is there now and just let all the charged shots give a full charged blast without wiping bubbles.
Like i said, my ideas come from a competitive mindset, absolutely nothing made for Casuals. Saying that players have different abilities&dextery doesn't matter at all
