1. I feel that there is too much of a divide between Pro Inbetween and Beginner levels of players, all "pro" players really need to DOMINATE are FEINTS,PARRIES,LIGHTS,HEAVIES based on how I've seen many play combos become pointless as they are read and countered easily, making you afraid to even attack which also inspires turtling. I feel that there is now too much focus on mind games compared to actual fighting.

SOLUTION I think there should be a large stamina drain on parries and feints, causing them to become used less often like more for openers and getting out of a sticky situation. Blocking and dodging needs to become more important for defensive strategies, then feints and parries add to that instead of completely overshadowing them.
As for the predictable combos that end up neglected because of this I think to combat this fighting styles need to be introduced in the form of different move sets for each heroes you can equip (say 3 for each hero) this will make things more varied and different because if someone gets too used to one move set you can just switch to another, this also adds another layer of depth to the game because its something more to learn. Either this or a combo lab, a good example of this would be that game, Remember ME.

2. Finally I think there's a serious problem with 4v4's because of doubles, heroes and feats. 4 Centurions anyone? Each heroes abilities times 4 or less presents a problem when you are going up against it, its not fun and would be quite difficult for newer players to learn to combat. Feats follow the same principle, 4 catapaults at the same time?! This occurring all falls to the player of course and that's the problem, you get people who would go there and that would not go over well with newer or older players as its just plain awful to deal with. Another issue with feats is that some classes have annoying combos of feints, Lawbringer for example can have 4 different types of grenades on him at the same time, all of them cause damage and then some damage stun and blind too, now imagine that with 4 Lawbringers all with the same feats equipped!!

SOLUTION I think teams should be forced to choose roles (VANGUARD,HEAVY,HYBRID,ASSASSIN) with all the heroes being released now there are more than enough to make varied combinations of heroes for both sides without a single double on either side, this will make teams communicate better from the start by deciding who pics what,all the classes will become important each in their own special way which could lead to some interesting battles. Now here's where the feats come in, to combat annoying feat double combos, I think feats should also be class specific as in each class uses their own feats for example, Heavies get to use passives that make them harder to kill, vanguards get to call down artillery , hybrids get to use support feats, assassins get to use feats to make themselves more deadly and their team.
