There we go again...
In my opinion you're barking up the wrong tree.
First. Nobody can be interested in longer fights with higher level pets as long as you get close to nothing for your efforts when you win and a hefty punishment when you lose. It's also frustrating to have to deal with lots of abilities which ain't correctly implemented or simply don't do what their descriptions say. In addition, those fights are way too long for events, especially when you have to fight those endurance uberpets that are just waiting for you in the trenches. And what about getting regularily paired up with an opponent whose pet is of a higher level than your own.
Second. It's quite interesting and fun to fight on those restricted low levels and try to get the best out of it. To me it's quite rewarding being paired up with an opponent whose pet is exactly built alike and then beating him with a 30 hp point margin without being favoured by the dice during the fight. You also learn a lot by this, basics.
Third. Could we all agree that this is a game of knowledge and skills. People have endured alpha and beta stages of this game while making tons of mistakes and learning a lot. Newcomers are at a disadvantage, that's the whole point, ain't it. Any game of knowledge and skills is unfair to the beginners, so there's nothing to yell about it, really. Your car is the fastest in training, you get pole for the race. You beat the crap out of other teams during the season, you get bye and homefield advantage in the play-offs. You win your play ball conference, you get paired up with the worst team qualified of the other conference. There is an established pattern.
True, there's a lot that should be changed. Ranking points, pairing algorithm, event rules, you name it.
Maybe let's do a tournament, level 6 pets only. Would probably solve a lot of problems and save a lot of tears. Cheers!
