Hi there,
I am not a game tester and I'm not sure what you as developers are looking for in feedback, but I am willing to to write some ideas on what I have experienced in playing the arena mode and what I would like to see improved.
1. Defence
I did not see the goaltending violation come into play. There have been occasions where my players or the opponent players had some situations that should have been goaltending. After playing the arena for a few days I did not see any goaltending come up although in other game modes goaltending is present.
Blocks and steals are very difficult to manage. It seems to be almost impossible to get the right timing for any of them, unlike in the other game modes.
2. Offence
The way the players shoot the ball is different every time, sometimes it is really laggy sometimes it moves too fast unlike how you play in any other game mode.
Getting the clutch to work is way more difficult then in other modes. I get the player in the right position, I press the button and then I have the surprise of seeing that the player is not in the position where it should have the clutch engaged and it doesn’t shoot the ball.
I have a 109 overall team and yet when it comes to scoring from 3-point shooting I usually manage one in three shots. However when I've played against a 99 overall player he used and underrated point guard and managed to shoot threes the way that Curry would be jealous
3. Rewards
I do not agree with the way that your for rewards at this point. First of all they are really not making any sense seeming like rewards that were offered in past campaigns not something that is necessarily useful to develop your team.
I think you should have better rewards, something similar to what you have in showdown where you get some new jerseys, new court, foam fingers or special players and tokens.
Also the arena points should be a worded differently in my opinion. If you are looking for people to join and play the arena mode, I think one arena point should be awarded for each game you enter and complete, and then if you managed to win the game or tournament you get extra points. This way you don’t feel like you've wasted your time, but still it is not like getting rewarded just for entering and abandoning a game
4. Don't end the game in a draw
There is no reason to end a basketball game in a draw. It happened to me three times and and it made no sense I've wasted 30 minutes without getting anything out of it. If you lose you are closer to ending the tournament by getting the number of losses or if you win your closer to ending a tournament in the number of wins. Ending in a draw has no benefit whatsoever so I suggest you have over time depending on the length of the match neither one minute or one one minute and a half.
5. The gift button
At the moment the gift button only displays a message that you should go on the social media pages related to the game. The button should either take you automatically to that page or just display the gifts and and who they are awarded to or just the gifts that are awarded to you.
6. Matching players
I believe that players should be matched regardless of their overall all team score. In real life basketball teams play against each other no matter how they rank and I believe the same should be here. It is not like the Warriors only play the Rockets. I am sure there are good players that will manage to defeat a better ranked team by getting some good plays.
Hopefully you'll find something useful in what time wrote above. I do not know if some of the problems are just related to the way the internet works, how the servers perform or if the phones that people play on are reason for this, but if it is of any use I can tell you that I am using a oneplus 6t and that my network connection although it is not 5G, it is a high-speed and reliable one.
