Well if XIII Leona is anything to go by, Max mode gives her two different projectile walls to hide behind in Baltic launcher and Excalibur, she can toss grenades faster, or close the distance and pressure with Grand saber, and she'd still get better Moon slashers for anti-airs. I recall reports saying Iori's EX fireball doesn't go anywhere so his Max mode just seems to improve his close game (maybe his EX overhead gets invul or seeks and that could improve his approach game as well). And Andy gets his slow projectile, a Far moving anti air and I'm assuming his EX elbows are at least mostly safe.
I feel given the current information about the game systems, no one playstyle will invaildate the others. Damage output seems alright, there's a good amount of ground game with better hitboxes for normal anti-airs. Max mode appears to give different characters different tool sets so far. I mentioned combos in my last post cause someone felt they are difficult to pull off, I feel that given time with the system we will see much more impressive stuff, and that it will come in all ranges of difficulty (something for the casuals and something for the combo makers, and more stuff in between) and more importantly that they aren't the be all end all of the gameplay.
