@Zards Honestly, the only thing you discussed that I take an honest issue with was:
"I also think that it was a mistake to enable the option to enchant armor in this Alpha, many players who did not know this, fought with people with enchanted items, who received no damage, and killed them easily, that was frustrating.
The enchanted items must have different colors, this is good for the game design, they would look better, armor and weapons with metallic colors, and very important for the identification of the items among the players, that would be at least fair, to know the power of the enemy in a fight."
Right off the bat, as someone who is color blind that would literally put me at an immediate disadvantage since if I'm the one attacking...I'll be broadcasting to them which tactics to not open with and prepping them with the knowledge of best dmg result attacks to use as well as knowing what dmg type I am most likely attacking with as I'd be holding a weapon of said dmg type, as well as show my commitment by insuring it had extra buffs.
In other words, using an identification system like that would result in one thing...an easy fix button for players already too lazy to insure they are ready for a fight before they go to places where odds are high they're going to get into a fight.
It's not fair allowing the other party to know what your strength and weakness, rather it's a way for people saying they just want a fair fight to, in reality, have the ability to know if they should run or they have an easy kill in their sights and it's safe for them to stay. Another player being more prepared then their opponent isn't unfair....it just means that they are...well....more prepared. So all the color scheme really does is punish those who insure they're prepared and reward the ones cutting corners in maintaining battle preparedness.
A far better fix, and one that doesn't require the first digit of code? Assume everyone you come across has every single skill and attribute buff on them from head to toe as well as operate from the mindset that if they are uber buffed like that being able to match those stat increases is priority as well as will steer your combat away from bad mistakes and giving away easy kills.
